kde environment does not start after emerge -u world

Message

muebi · Post by **muebi** » Thu Aug 27, 2009 11:45 pm

Hi,

I updated my system using emerge -uD world and I did a revdep-rebuild afterwards to fix broken packages.
Now, when I reboot the x server does not start anymore leaving me at the text-based login screen. How can I fix this problem?

I looked at /var/log/messages and there are some lines saying:
kdm[4384]: X Sever died during startup
kdm[4384]: X Sever for display :0 can't be started, session disabled

Thanks.

When you start X the start-up messages and also error messages end up in the file ~/.xsession-errors
This file might tell you what doesn't work with your X setup.
I would also suggest going through your emerge log under /var/log and look for clues as to what package that you installed might have affected your setup in this way.

Good luck

You can also look for error messages in the /var/log/Xorg*.log files.

If you upgraded xorg-server from < 1.5 to >=1.5 then the problem probably lies there. There were some big changes and usually the new X server won't start with the old config files. Here is the upgrade guide.

If I startx then it says something like

(EE) Failed to load module "freetype" (module does not exist, 0)
(EE) Failed to load module "type1" (module does not exist, 0)
(EE) No devices detected

Fatal server errors:
no screens found.

Does this point into the direction that I updated to a version of Xorg > 1.5 and, hence my xorg.conf does not work anymore?
I am also not sure which steps I should proceed (in the upgrade guide) to get things running again. Is it just some line in the xorg.conf that needs to be replaced or do I need to mess around with the kernel now?

On my system, I have a complete record of what's been emerged in /var/log/emerge.log. Hopefully you can look in that file and see if you upgraded xorg-server recently and also what version you upgraded from.

The other avenue of approach is to Google for the error message you found. The X.org site has this to say:

You get an error message like:
Code: Select all
(EE) No devices detected.
Fatal server error:
no screens found
It is very likely that your xorg.conf file doesn't contain the correct driver(s) for the chipset(s) in your system or that your chipset isn't supported by any of the drivers.
You can check for the detected devices in the log file (in most cases /var/log/Xorg.0.log) by looking for lines like:
Code: Select all
 (--) PCI:*(1:0:0) Neomagic Corporation NM2200 [MagicGraph 256AV] rev 32, Mem @ 0xfd000000/24, 0xfe800000/22, 0xfec00000/20 
In this example the active video device (the one with the *) is a Neomagic NM2200 video chip. In order to get this chipset to work you'd have to use the neomagic driver.
If you are using a distribution you should rerun its configuration tool. If there is no such tool, or if it keeps configuring your Xserver wrong you may want to try xorgcfg, the graphical tool shipped with Xorg. You can also let the server generate a config file: as root just run X -configure.
Please note: If you appear to use the correct driver and you still keep getting this message it is very likely that your chipset isn't supported (yet). In this case you may try the vesa driver or - if this doesn't work - the vga driver. However both are entirely unaccellerated.

It would be good to know what video driver you're using. I use the Nvidia driver which is called "nvidia". I can see if it is loaded by doing:

Code: Select all

$ lsmod | grep nvidia

I can try to load it with:

Code: Select all

$ sudo modprobe nvidia

The rmmod program can be used to unload modules. It could be (best case) that all you have to do is load your video driver.

From my /var/log/emerge.log it seems emerge updated xorg-server from version 1.3.0.0-r6 to 1.5.3-r6 if I understand this correctly

I have the Intel Mobile 4 driver AND ATI Tech. Mobility Radeon HD 3650 and I remember that this was giving me a hard time when I installed gentoo on this box about a year ago...

BitJam · Post by **BitJam** » Fri Aug 28, 2009 2:13 am

Good! Now we know what the problem is.

Here is a very long thread dealing with this issue. You can see that you are not alone.

I would suggest trying to follow the upgrade guide I linked to before. You can tell if you already have evdev in your kernel with:

Code: Select all

$ grep EVDEV /usr/src/linux/.config

muebi · Post by **muebi** » Fri Aug 28, 2009 2:33 am

It seems that I have EVDEV already built into the kernel. I'll try following the upgrade guide tomorrow and report back with the results.
Do I need to change entires in my /etc/make.conf as suggested in the thread? The upgrade guide does not say that... I'm confused....

Can anybody tell me what fdi file I have to choose in my case? I have a laptop with US keyboard, mouse, touchpad plus the "red IBM/Lenovo control nipple"....

ls /usr/share/doc/hal-0.5.11-r9/ gives:

I keep poking around following some ideas in the forum but I am still stuck and I don't understand what the real problem is.

startx always gives

(EE) No devices detected.

Fatal server error:
no screens found

d2_racing · Post by **d2_racing** » Sat Aug 29, 2009 4:15 am

Hi, you need to add evdev.

Like this :

Code: Select all

INPUT_DEVICES="keyboard mouse evdev"

After that, run this :

Code: Select all

# emerge -auDNv world

and retry

muebi · Post by **muebi** » Sat Aug 29, 2009 10:10 pm

I tried what you suggested but still the same problem.
I can get rid of the freetype and type1 errors by commenting these lines but I still get the "no devices detected" error and X won't come up.

Hi,

I really need to get this going again. Is there any fallback option in case xorg-server1.5 doesn't work with my configuration or whatever

d2_racing · Post by **d2_racing** » Mon Aug 31, 2009 5:43 pm

Yes, boot without any /etc/X11/xorg.conf

You will endup with the VESA driver and a US keyboard by default.

muebi · Post by **muebi** » Mon Aug 31, 2009 6:25 pm

I just renamed my xorg.conf file and tried startx without any config file. Is this what you meant?
It says new driver is VESA but then

(EE) Failed to load module "fbdev" (module does not exist, 0)
(EE) No devices detected.

d2_racing · Post by **d2_racing** » Tue Sep 01, 2009 11:29 am

Ok, plz add this fbdev inside your /etc/make.conf :

Code: Select all

VIDEO_CARDS="fbdev fglrx radeon intel vesa vga"

Also, you should disable the framebuffer feature inside your kernel config, just to be sure that you can start your X server at least without any gadgets.
