system state [solved]

[John R. Graham]

Could you post the values of the INPUT_DEVICES and VIDEO_CARDS variables in /etc/make.conf, please? Also, the contents of /etc/X11/xorg.conf would be helpful.

- John

[idella4]

john thanks. We're almost there. I was about to do part of what you requested. Now, at bootup I have /dev/input/mice and mouse 1 and mouse2 and a couple of others. We're on the same page. I've looked at xorg.conf. I know that genny has made all the devices including the mouse.
It's clearly an xorg issue to correctly configure X using the mouse. So, in /etc/make.conf, INPUT_DEVICES is blank. I suppose this must be a new setting since it used to work perfectly well without it. VIDEO_CARDS="fbdev i810 nv nvidia tdfx trident vesa vga". This is clearly the right path.
xorg.conf

Code: Select all

Section "ServerLayout"

# "SendCoreEvents".
    Identifier     "Simple Layout"
    Screen         "Screen 1" 0 0
    InputDevice    "Mouse1" "CorePointer"

    Identifier     "Mouse1"

    Option         "Device" "/dev/input/mice"
# When using XQUEUE, comment out the above two lines, and uncomment
    Option         "ZAxisMapping" "4 5 6 7"
# Emulate3Buttons is an option for 2-button mice
    Option         "Emulate3Buttons"
#    Option "Emulate3Timeout"    "50"
# ChordMiddle is an option for some 3-button Logitech mice
    Option         "ChordMiddle"
EndSection

No need for the whole thing. Most lines start with # and this is the relevant part.
It looks like the answer lies in INPUT_DEVICES in make.conf being blank. gentoo is a moving target. This was all covered when I last used it. I may as well look at man make.conf
So I await the required entry with bated breath.

No need for the whole thing. Most lines start with # and this is the relevant part.

Well, actually yes. It's important to be precise. Please post the output of

Code: Select all

egrep -v '^(#|$)' /etc/X11/xorg.conf

If there are requests to post something big, please use http://pastebin.com and paste the URL here.

My make.conf contains exactly what I need according to the output of lspci.

Code: Select all

VIDEO_CARDS="radeon"
INPUT_DEVICES="evdev"

Please set yours appropriately, and run

Code: Select all

emerge -uDNav world

Whenever xorg-server is emerged or updated, you need then re-emerge your x11-drivers

Code: Select all

emerge app-portage/portage-utils && emerge -1av $(qlist -IC x11-drivers)

Glad you're making good progress.

[idella4]

Mike, I found this http://en.gentoo-wiki.com/wiki/X.Org/In ... UT_DEVICES
Yes it cites evdev which I've never heard of. This site says to run

Code: Select all

emerge -pv xorg-server

and then says

and look at the the output following INPUT_DEVICES,

[ebuild N ] x11-base/xorg-server-...USE="..." INPUT_DEVICES="...." VIDEO_CARDS="..."

which it doesn't do.

Code: Select all

Susie / # emerge -pv xorg-server

These are the packages that would be merged, in order:

ok 6 packages isn't so bad. I'll do it.That won't take long. The next should be quick too I think. Then I reboot and everything should be well and truly set.


One minor thing. How do you setup kde to go in on bootup again. I've got xdm in rc bootup default, xdm.conf sayd DISPLAMANAGER='kdm" and
.xinitrc says startkde, I think that's right. what is missing? and I never did get a solution to chroot in gentoo. The mysteries of gentoo!

[idella4]

UNBELIEVABLE UNBELIEVABLE UNBELIEVABLE.

iT MADE NO DIFFERENCE. all that updating and providing and it can't configure the mouse. Oh my.

WILL SOMEONE PLEASE FIND NEDDY

[Mike Hunt]

You still need to re-emerge x11-drivers after re-emerging xorg-server.

And also set your video device driver correctly in xorg.conf please.

Also post what video device you have, as there could be misconfigurations in kernel.

[NeddySeagoon]

idella4,

When you have input devices and video devices you need missing from Xorg, you may add them to your INPUT_DEVICES and VIDEO_DEVICES in make.conf
and use

Code: Select all

emerge -1 xf86-input-... xf86-vides...

to build them straight away. The entries in INPUT_DEVICES and VIDEO_DEVICES will ensure they are maintained by portage.

As well as evdev for Xorg, you need evdev for your kernel. Check that you have files named like /dev/input/eventX where X in a number. If not, you need to fix yor kernel.
Auto configuration of of input devices relies on hald and dbus being running - they should both be in your defualt runlevel.
Look with

Code: Select all

rc-update show

add them and start them if needed.

Lastly, Xorg has changed its ABI recently. That requires all the video and input drivers to be rebuilt to match the new ABI.
You will get ABI mismatch errors in /var/log/Xorg.0.log if thats an issue.

It would be good if you can post that file.

Code: Select all

emerge wgetpaste
wgetpaste  /var/log/Xorg.0.log

then tell us the URL it gives you.
Thats your /var/log/Xorg.0.log file on the web for all to see.

[aguettinger]

As an addition to all the above, don't forget you always have to reinstall nvidia-drivers after upgrading a kernel.

emerge -av nvidia-drivers

[idella4]

duplication

[idella4]

neddy, I knew you could do it. thanks.
wgetpaste is a handy tool and new to me. I ran it and it indicates http://dpaste.com/125269/
I've added the missing hald and dbus. I have to reboot to see if it will work. According to Murph's law, I'll need to adjust the kernel for evdev which is new to me. I suppose that answers the question what is a pastebin. Not having come across it before I have no idea how to do that.
What is an ABI?
next a reboot.

[aguettinger]

The evdev is pretty important, because the new hal config works with evdev.

Make sure that you have this inside your kernel :

Code: Select all

Device Drivers 
       ->Input device support 
               ->Event interface 

That's all that is needed kernel-wise for evdev to work. If you don't have it, enable it and rebuild.
Also, from your Xorg.log is states GLX is not loaded. You need to re-emerge nvidia-drivers.

[idella4]

duplication

[idella4]

aguettinger yes ok thanks. You've looked at the log already. Like to look at the next one.
It still doesn't work after all that.
STUBBORN STUBBORN STUBBORN
tHE CHANGES HAVE FIXED SOMETHING. oN REBOOT THE SETTINGS ALREADY THERE GOT IT to boot into kdm which is a step. The mouse still doesn't work. From here it's clearly fixable, but how. There's now a new log to view http://dpaste.com/125275/
genny made all devices. In /dev/input there is mice amd mouse1 and mouse2 and event0 to 2 or three. There are some there so the kernel should be right

Code: Select all

  │ │    < >   Joystick interface                                              │ │
  │ │    <*>   Event interface                                                 │ │
  │ │    < >   Event debugging

no problem there. the xorg log. That's where the deficit lies.

(==) Not automatically adding devices
(==) Not automatically enabling devices

in early stage, is a worry

(II) LoadModule: "freetype"
(WW) Warning, couldn't open module freetype
(II) UnloadModule: "freetype"
(EE) Failed to load module "freetype" (module does not exist, 0)

(==) AIGLX enabled

is not fatal. Is there a freetype package missing? This log says glx is loaded

(II) LoadModule: "mouse"
(II) Loading /usr/lib/xorg/modules/input//mouse_drv.so

(II) AIGLX: Screen 0 is not DRI2 capable
(II) AIGLX: Screen 0 is not DRI capable

not fatal but how can it be fixed?

(II) UnloadModule: "mouse"
(II) UnloadModule: "kbd"
(WW) Open ACPI failed (/var/run/acpid.socket) (No such file or directory)
(II) No APM support in BIOS or kernel

is a worry. How can it be fixed? xorg is fairly complex, many modules. The mouse doesn't work, I think that's all but there may be more according to this, Does anyone know?

[aguettinger]

What is the output of eselect opengl list?

opengl should be set to nvidia to use the GLX from the nvidia-drivers.

eselect opengl set nvidia

Then restart X. Hope that solves the GLX errors.

Now to the keyboard mouse problems. There should be a message LoadModule "evdev" in you Xorg.0.log which is missing, so something with evdev/hal still is not working. Can you give the output of

rc-update show

[idella4]

andy, yes ok. I hope you can see this through, neddy would be impressed. We have

Susie linux # eselect opengl list
Available OpenGL implementations:
[1] nvidia
[2] xorg-x11 *

opengl should be set to nvidia to use the GLX from the nvidia-drivers.

So how do I set it to nvidia?

Code: Select all

Susie linux # rc-update show
            bootmisc | boot
             checkfs | boot
           checkroot | boot
               clock | boot
         consolefont | boot
                dbus |      default
                hald |      default
            hostname | boot
             keymaps | boot
               local |      default nonetwork
          localmount | boot
             modules | boot
            net.eth0 |      default
              net.lo | boot
            netmount |      default
           rmnologin | boot
           syslog-ng |      default
             urandom | boot
          vixie-cron |      default
                 xdm |      default

just like neddy suggested, hald and dbus are added

[aguettinger]

Ok, to switch to nvidia GLX do

eselect opengl set nvidia

Then I see hald is running, that's good. I saw in your make.conf from the last page you don't have the hal USE flag set, if not you should add it to your make.conf and do again.

emerge -uNDav world

EDIT: Especially double-check that your xorg-server is emerged with the 'hal' flag, else it's not gonna work.

We are getting closer. You updated over 2 major versions of Xorg so that's why some configurations changed. We all had to go trough that.

Next, make a file /etc/hal/fdi/policy/10-x11-input.fdi
with the following contents (that's where hal looks for the config for mouse and keyboard, they can be adjusted, let's try this for start)

Code: Select all

<?xml version="1.0" encoding="UTF-8"?> 
<deviceinfo version="0.2"> 
<device> 
    <!-- Mouse configuration --> 
    <match key="info.capabilities" contains="input.mouse"> 
      <merge key="input.x11_driver" type="string">evdev</merge> 
    </match> 

    <!-- Keyboard configuration --> 
    <match key="info.capabilities" contains="input.keymap"> 
      <append key="info.callouts.add" type="strlist">hal-setup-keymap</append> 
    </match> 
    <match key="info.capabilities" contains="input.keys"> 
      <merge key="input.xkb.model" type="string">evdev</merge> 
      <merge key="input.x11_driver" type="string">evdev</merge> 
      <merge key="input.xkb.layout" type="string">us</merge> 
      <merge key="input.xkb.variant" type="string"></merge> 
      <append key="input.xkb.options" type="strlist"></append> 
    </match> 
  </device> 
</deviceinfo> 

If you need to make adjustments for mouse and keyboard layout later, you can get more info from the Xserver1.5 sticky thread.
Then make a backup copy of your /etc/X11/xorg.conf
I made some changes to your xorg.conf according to mine, so try this xorg.conf.

Then restart your X and pastebin the Xorg.0.log

[idella4]

andy, right, you seem to be on the right track. I wonder why neddy didn't mention this if it's required to work.
I found out how to set it by trying the correct entry, so that's done. I've made the new policy file. That's pretty intricate. How did you come to know about such a file? I'm running the emerge world, only six packages so that's good. This updating is so complex. I haven't done it for a while and I suppose I expected it to occur more easily. In gentoo it's very manual even with all the portage and other tools. It's so intricate.

A new xorg.conf. Hmmm, well I may as well try it. Just how do you restart X?? I've seen it suggested a couple of times and have tried it in the past by guessing so what is the required command? A reboot is next and I hope that this protracted fix will finally end.

One minor point I get

Code: Select all

IMPORTANT: 1 config files in '/usr/share/config' need updating.

I've run etc-update. How do you check this file outside of /etc ?

Well I rebooted and get some errors of old, so rebooted again, and it went in. THE MOUSE WORKS
greetings from genny

congratulations andy.

There is a glitch. When you move the cursor to the far right and beyond, the desktop starts shifting left, leaving a region of black. The same with moving the cursor down and beyond. It's not set in position. Is this the screen settings in xorg.conf? So How do I restart X? Otherwise it works, and I've got nvidia full 3d acceleration for the first time unlike in the other 18 month old dentoo with kde3. It must be from setting opengl to nvidia. A great new setting

and andy, if you really want to impress, try this http://forums.gentoo.org/viewtopic-t-803188.html

Otherwise, it's time to close off this protracted thread and move to the next issue which actually uses a gentoo system to do something advanced. I'll wait until I get a reply

[NeddySeagoon]

idella4,

It seems you are well on the road to recovery.

I didn't mention all the things you need to migrate to Xorg 1.5.3 and later as I wanted to see your Xorg.0.log first.
It would save me a lot of extra typing.
The freetype, DRI and DRI2 warnings can be ignored.

freetype has been removed from gentoo - you can remove it from your xorg.conf to get rid of the warning.
nVidia does not use the Xorg DRI at all, it achieves the same thing its own way. Ignore those warnings.

Your xorg is running with a viewport into the desktop. The desktop is configured to be larger than the screen, so the screen shows a viewport onto the desktop. When you approach the edge of the screen, the viewport moves to show more of the desktop in the direction of mouse movement.

Post (or pastebin) your xorg.conf and the Xorg.0.log it produced. Then we can tell you how to fix that.

Oh, an ABI is an Application Binary Interface. Its the standard that an application uses to communicate between its various parts. All the parts normally have to use the same standard or they won't work together. When the standard is changed, you need to rebuild all of the application. Xorg does thell in its log if you have this issue - you don't

Glad it worked.
As I mentioned in my last post, if you want to know more about how to configure mouse and keyboard via hal/evdev, then the sticky thread in the Desktop environment subforum is the best place to look at.

I don't know about the chroot problem. I always used chroot from the install cd.

thanks neddy and andy. Read back at andy's entries and you'll see he took mine and modified it and pasted it. That's the xorg.conf, and an Xlog is http://dpaste.com/125275/ from yesterday just before the last fix, and the current http://dpaste.com/125677/
Strange, I was in suse for extraneous reasons, chroot into genny like I've been doing all week to work on her (remember gentoo has a broken chroot) and got no connectivity, just gone, which is what happened 18 months ago. Happily I booted in and she's healthy. The mysteries of suse, but that's another forum

idella4,

I need a selfconsistent xorg.conf and Xorg.0.log as they are now, with no doubts and no chance of them not being a matching set.

[idella4]

neddy, yes ok.

xorg.conf

Code: Select all

    EndSubSection
    SubSection     "Display"
        Viewport    0 0
        Depth       16
        Modes      "640x400"
    EndSubSection
    SubSection     "Display"
        Viewport    0 0
        Depth       24
        Modes      "1280x1024" "1024x768" "1600x1200"
    EndSubSection
EndSection

and the xorg log @ http://dpaste.com/126129/

I had a quick look through, and I know it means more to you than I can decipher. It mentions flaws in dri and dri2 modules which can be ignored, that leaves ACPI. thanks for looking at it. I'm keen to tie this thread off, too long already. I've been looking closely at a virtual machine package and its methods and it cites completely alternative graphical support packages to xorg. It would be enough to get a handle on xorg. I'd like to try one out, but I think it's beyond the expected level of knowledge of users and helpers in the gentoo forum. What do you think?

idella4,

Going through your Xorg.0.log line 89-90

Code: Select all

(II) LoadModule: "freetype"
(WW) Warning, couldn't open module freetype

Xorg is automatically trying to load "freetype" but its obsolete and no longer in Gentoo. Ignore it.

Line 107

Code: Select all

(II) LoadModule: "dri"
(WW) Warning, couldn't open module dri
(II) UnloadModule: "dri"
(EE) Failed to load module "dri" (module does not exist, 0)
(II) LoadModule: "dri2"
(WW) Warning, couldn't open module dri2
(II) UnloadModule: "dri2"
(EE) Failed to load module "dri2" (module does not exist, 0)

Xorg is automatically trying to load dri and dri2 but the nVidia driver does not provide them as it does not use them.
These errors can safely be ignored.

Line 161 - this has to do with your viewport issue.

Code: Select all

(II) NVIDIA(0): Validated modes:
(II) NVIDIA(0):     "1280x1024"
(II) NVIDIA(0):     "1024x768"
(II) NVIDIA(0):     "1600x1200"
(II) NVIDIA(0): Virtual screen size determined to be 1600 x 1200

Xorg sets up to drive the screen in the modes listed there, so the desktop size will be 1600 x 1200.

In your xorg.conf you have

Code: Select all

     SubSection     "Display"
        Viewport    0 0
        Depth       24
        Modes      "1280x1024" "1024x768" "1600x1200"
    EndSubSection 

The order of the Modes is important. The first mode is what xorg will present you with when it starts, so you have a 1280x1024 viewport onto a 1600x1200 desktop.

Reorder your Modes to be

Code: Select all

Modes    "1600x1200"  "1280x1024" "1024x768" 

and Xorg will start with a 1600x1200 viewport on a 1600x1200 desktop, so it just fits. If you never want to use 1600x1200, remove it from the Modes line.

You have the defualt US keyboard layout, as the very last line of the log says

Code: Select all

(**) Option "xkb_layout" "us"

thats ok if you actually have a US keyboard.
