 Posted: Fri Jul 17, 2020 3:01 am Post subject: X session fails with ATI Radeon HD 4670 - KMS /radeon driver |
 |
|
Hi everyone,
I'm in trouble with an iMac (mid 2010) and its GPU ATI Radeon HD 4670 256 Mb. It seems the radeon free driver fails with it.
I've tried a plenty of GNU/Linux distributions. I could perform a complete install only with Gentoo, Debian 10, Ubuntu 20 and openSuse (15.1, successfully upgraded to 15.2 recently, and the open release Tumbleweed). In all cases, I need to add the "nomodeset" or "radeon.modeset=0" kernel parameter on boot in order not to get a frozen black screen right after loading the initramfs. Other distros I've tested give a black screen anyhow on Live CD; Debian and Ubuntu do the same on first post-install boot.
With opensuse, I can open a proper X session with desktop environment, still with nomodeset or radeon.modeset=0 parameter. It's perfectly suitable despite some display jaggedness. Tumbleweed even handles enjoyable transparency effects on Plasma desktop.
On Gentoo, install DVD could not load graphic mode and the whole install process was somehow epic, with several yet unclear hangs during world updates, kernel builds and grub installs. Boot on two installed 5.4.48 custom kernels ends up with kernel panic. I've eventually resorted to use a pre-built gentoo-kernel (5.4.40), capable of avoiding black screen (needless to say, with one of the imperative kernel parameters) and have a flawless boot (woah!), but X server fails to start. (I have no display manager installed)
Here are the last lines of Xorg.0.log:

though radeon module does exist... Is it because modesetting is deactivated on boot, or am I missing something?

ATI proprietary driver should not be suitable since it only supports up to Xserver 1.12 and Linux kernel 3.4 (see https://www.amd.com/en/support/graphics/amd-radeon-hd/ati-radeon-hd-4000-series/ati-radeon-hd-4670 ). However, an install trial results in:
| Code: | Check if system has the tools required for installation.
fglrx installation requires that the system have kernel headers. /lib/modules/5.4.40/build/include/linux/version.h cannot be found on this system.
One or more tools required for installation cannot be found on the system. Install the required tools before installing the fglrx driver.
Optionally, run the installer with --force option to install without the tools.
Forcing install will disable AMD hardware acceleration and may make your system unstable. Not recommended. |
It doesn't find the headers, although they're installed (I could not figure out where they are myselg, I thought they were part of kernel sources, but actually they are a separated package; those are cryptic considerations for me and I don't think it's key to solve my problem).
My technical skills are restricted, but I'd really like to figure out why and how others fail when openSuse succeeds. Is it a specific kernel patch or parameter? And if it does, shouldn't be Gentoo able to do the same, or shouldn't there be any workaround?
Any idea is welcome to help investigate that issue.

just to point out, I mustn't have nomodeset or radeon.modeset=0 set in your kernel or less the driver must probably won't work.
can you also post the entire .config?
note that you don't need CONFIG_DRM_AMDGPU at all

(I run a local rsync Gentoo mirror, see https://wiki.gentoo.org/wiki/Local_Mirror , it works without a problem)
About your second message, I'm not sure to understand what you actually mean. To make it clear in case it's not, adding nomodeset or radeon.modeset=0 kernel parameter on boot is the only way I've found not to have a frozen black screen immediately. OpenSuse handles it and manages to open X session (with those two related messages "[drm] VGACON disable radeon kernel modesetting." and "drm:radeon_init [radeon]] *ERROR* No UMS support in radeon module!" on boot). |

from your dmesg:
| Code: | | [ 10.286269] [drm:init_module [radeon]] *ERROR* No UMS support in radeon module! |
as said, you cannot load drm without modeset.
the reason modeset doesn't work is because you are missing the relevant firmware in the kernel.
consult this for more information.

I've managed to make a new kernel 5.4.48, retrieving config from gentoo-kernel and adding the firmware matching with my GPU, "radeon/R700_rlc.bin radeon/RV730_smc.bin radeon/RV710_uvd.bin radeon/RV730_me.bin radeon/RV730_pfp.bin", according to the page you mentioned. I still have a black screen on boot without "nomodeset"; with nomodeset, just like previously, boot is ok but X returns the same error.
Complete config file : http://dpaste.com/1J8RTH6
It seems not as clear as you say, or I do miss something. And the fact is that openSuse (only, until now) can have a X session working with the same conditions. |

have you installed the fw pkg, e.g. sys-kernel/linux-firmware?
can you provide dmesg from the bad boot? either via ssh or syslog-ng and such?

Now "radeon kernel modesetting enabled.", but I still get a blackscreen (now some seconds after openrc is launched; before, I could only see "loading initramfs").
| DaggyStyle wrote: |

I can't find it:
| Code: | $ eix *710*
No matches found
|
Or do you mean adding also the firmwares blobs for RV710 mentionned on the Radeon wiki's page?

the dmesg show the module is loaded successfully.
if you disable X, do you get to login on screen?

X isn't enabled. I have no display manager installed, I need to launch it manually.
I can't get to login screen if I don't deactivate modesetting. |

try disabling CONFIG_FB_SIMPLE and check again
if not working try kernel 5.4.48 or kernel 4.19.129

Pums,
Please pastebin /var/log/Xorg.0.log so we can see what Xorg does when it starts.
| Code: | [ 13.134529] fbcon: radeondrmfb (fb0) is primary device
[ 13.175111] Console: switching to colour frame buffer device 240x67
[ 13.182091] radeon 0000:01:00.0: fb0: radeondrmfb frame buffer device |
says that your kernel is probably OK.
Your root filesystem is mounted at
| Code: | | [ 5.493167] EXT4-fs (sda10): mounted filesystem with ordered data mode. Opts: (null) |
which is a long time before the radeon drive is initalised, so I guess you have in set as a module. That's fine.

Previously, I tried to launch "startx" "blindly" twice (though I've no screen, I can access ttys, login, run commands...). In case it case help, these are the two Xorg.0.log I've gotten: http://dpaste.com/2DGQHND and http://dpaste.com/1A6W6FT. |

I'm currently using 5.4.48. I could not make custom kernel from 5.4.40 since with gentoo-kernel sources are not available (I use default last stable packages in my whole world set). As stated before, I retrieved gentoo-kernel config, oldconfiged it on gentoo-sources 5.4.48 and added the firmwares.
I may try to make a new 4.19.129 kernel if nothing else works but actually it's long and "painful" with that comp (as I've said in my first message, it often hangs for unknwon reason on large building processes; last night yet, It hung during gcc update). Why do you think it'd work with that kernel? |

it isn't far fetched that a kernel will have a bug.
if your system hungs during load, I think you should look at it first as it might have a connection to what you see.
I had a laptop with gentoo on it which misbehaved because the gpu fan has wore out.

Dbus isn't even installed; but X doesn't need it. For the moment, I've installed Lumina desktop that doesn't need it either (see https://wiki.gentoo.org/wiki/Lumina. |

you have dbus errors in Xorg.log, bot sure how much it is related

Pums,
Your log ends with
| Code: | | [ 557.528] (II) Server terminated successfully (0). Closing log file. |
That means that Xorg started properly, its using the radeon driver, found nothing to do and quit.
Run | Code: | | emerge -1av twm xclock xterm |
Its a number of small packges.
When that completes, I expect startx to show you three xterms and an analogue clock all wrapped up in twm.
twm only uses the primary mouse button.
If you have a ~/.xinitrc, rename it so its not found.

In absolute terms it is not. But in the specific case of this mac and its GPU, considering that I could not have X working properly with anyone of the numerous distributions I've tried, among them Debian 10 (with Linux 4.19), Fedora 29, 30, 31 and 32, Manjaro, Bodhi Linux 5.1, Mageia 7.1, Linuxmint 17, Linux Lite 4.8,, (X)Ubuntu 18 and 20, and considering that openSuse does it from Leap 15.1 (Linux 4.19) to Tumbleweed (5.7), including Leap 15.2 (5.3.18 ), it seems to me a bit far fetched to suppose it'd be a version specific kernel bug. I may be wrong since I'm a newbie and sure I don't know and misunderstand many things, I aim to learn and understand.

It's an iMac, impossible to open and have a peek inside without a professional equipment I have not, would cost an arm and a leg to have it done by a professional, that old computer doesn't worth it anyway.
I hope it's not a more specific hardware issue like the one you've had. Nevertheless, macOS still works perfectly on it and I've never had a problem of such but on Gentoo.
I guess it must be full of dust inside, I'll have to do with it (I could take off a handful of dust from the ram compartment which is the only screw closed part). The "case" (I don't know if it's the proper word) easily heats, I presume it can explain it hangs during hard loads. However I don't know how I can check this out. The screen freezes, ssh stops, I can't do anything but a hard reboot. I'll try reducing MAKEOPTS from -j5 to -j3 (it's a quadcore).

I have already those packages installed (I always install them along with Xserver since they are necessary to start a basic X session).
I have two regular users accounts, one has .xinitrc set for starting Lumina, and the other doesn't have .xinitrc. It does not change anything.
I don't think it's the problem anyway: when the server says it terminated successfully, my screen is totally black since boot time (it becomes black after displaying some regular lines of openrc launching services). I've started X "blindly", I mean with absolute black screen, I do the same I would if display was ok: ctrl+alt+F2, username, password, startx. but I can't see anything on the screen.

Pums,
You can keep an eye on temperatures with lm-sensors.
Thermal problems can lead to system lockups.
About the only thing to do as you don't want to open the box, is reduce the thermal load.
You can do that by reducing to say -j2 or -j3.
As you have all the possible drivers for your Radeon card installed, lets try a different one.
| Code: | [ 379.205] (==) Matched radeon as autoconfigured driver 0
[ 379.205] (==) Matched ati as autoconfigured driver 1
[ 379.205] (==) Matched modesetting as autoconfigured driver 2
[ 379.205] (==) Matched fbdev as autoconfigured driver 3
[ 379.205] (==) Matched vesa as autoconfigured driver 4 |
Modesetting is nice and simple.
Make a file called /etc/X11/xorg.conf with the content
| Code: | Section "Device"
Identifier "OnBoard Radeon"
Driver "modesetting"
# BusID "pci:bus:dev:func"
EndSection |
Its possible you mad need to fill in the BusID entry.
With that file in place, Xog will use the modesetting driver or fail.
Run startx (no reboot required) and pastebin the log. I would be happy for you to get a picture with any driver right now.
