Display only offers 800x600 resolution

Post by ttemsk » 2020/02/09 21:21:50

Dear gurus, I've been setting up a CentOS 7 system as a platform for Microsemi FPGA tools. I have more experience in the Debian branch, but even there I try to be more like an end user than a system specialist. This is a laptop with a built-in 1920x1080 screen, and a dual display adapter with Intel HD530 + GeForce GTX 950M.

After installation with the Gnome desktop the system offered 800x600 as the sole available resolution, after which I installed the NVidia proprietary drivers + Bumblebee, although lack of the correct driver was probably not a problem to begin with. The installation was from ElRepo as per instructions found in another thread here. After the driver installation still only 800x600 is available. Anyway, lspci indicates that the graphics cards are recognized:

I have learned that EE's in the Xorg.0.log file indicate errors and WW's indicate warnings. Obviously there is something wrong, but I'm not familiar enough with the X-system to understand precisely what goes amiss.

Any help is highly appreciated. I don't really need the 3D which the NVIDIA driver might provide, but it would be nice to get the 1920x1080 2D resolution.

If you don't want to use the dGPU then you don't need the nvidia drivers. Besides, in an Optimus system the notebook's display is always driven by the iGPU. When the dGPU is used it copies its display surface to the iGPU's framebuffer for display.

Re: Display only offers 800x600 resolution

Thank you for your insight. I agree that the nvidia driver is not necessary if I don't need 3D. However, the 800x600 was the sole available resolution already fresh after the CentOS installation, when I believe Nouveau was the active driver. Installing the nvidia driver was my (misguided) attempt for remedy.

During the CentOS installation time did not know what Nouveau is, or that it acts as the default nvidia driver - I googled up the information only after the problems showed up. The graphical installer did not work, so I performed installation via the text-based one. The experience made me suspect that the default drivers are not able to handle my graphics card, and made my threshold low to look for better drivers.

Now I'm curious about what may the belowe lines (from the Xorg log) be symptoms of?

Code: Select all

 35.723 (EE) Unable to find a valid framebuffer device
...damn, it's too difficult to copy-paste other snippets on this smartphone ... I'll be back in a minute.

Ok here we go: I'd be curious about what causes these symptoms in the Xorg log file:

Code: Select all

 35.723 (EE) Unable to find a valid framebuffer device 

Code: Select all

 35.731 (EE) Screen 0 deleted because of no matching config section.
 35.731 (II) UnloadModule: "modesetting" 

Code: Select all

35.731 (EE) Screen 0 deleted because of no matching config section.
35.731 (II) UnloadModule: "fbdev"
35.731 (II) UnloadSubModule: "fbdevhw"
...and especially:

Code: Select all

35.734 (EE) NVIDIA(G0): GPU screens are not yet supported by the NVIDIA driver
35.734 (EE) NVIDIA(G0): Failing initialization of X screen
35.734 (II) UnloadModule: "nvidia"
35.734 (II) UnloadSubModule: "wfb"
35.734 (II) UnloadSubModule: "fb"
35.734 (II) UnloadModule: "nouveau"
35.734 (II) Unloading nouveau
I assume Xorg recognizes the modules which are causing the errors and therefore unloads them, but I don't know Xorg so that I could tell whether my assumption is true, and even less what may cause those errors. If this is easily seen by someone already knowledgeable about Xorg, any help is appreciated.

First of all, you should remove 'nomodeset' from the kernel command line, because the intel driver requires modesetting. I also suggest to uninstall the nvidia driver. You may even want to disable the dGPU in the BIOS.

(So that someone else googling for a solution could benefit from this effort: my laptop is Asus X550V )

Thank you for the suggestion. The least effort way to remove the nvidia-related changes was to re-install the CentOS fresh again, once again using text-based installer as the graphical one refuses to work. Only 800x600 available on Gnome with the default installation, and the Xorg.0.log had developed a new error, something like

Code: Select all

open /dev/dri/card0: No such file or directory
(I lost the exact message, because I blundered with saving my draft post).

Then for your suggestion:
- Edited /etc/default/grub and removed the item 'nomodeset'.
- As per the 'Grub2 howto' in these CentOS pages, executed

Code: Select all

grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg 
- Rebooted

The booting process hung up for a reasonably long time, but ultimately the Gnome desktop appeared at the desired 1920x1080 resolution. There was a message box "A problem has occurred. A problem in kernel package has been detected". But all relevant display modes are now available, and the system seems to be functional. This is a huge leap forward. Thanks a lot!

Next I'll try to figure what's with the kernel package problem. At least the Xorg.0.log seems to contain no errors any more. The voyage continues....

I would suggest removing rhgb quiet from the kernel command line too. Those options suppress the boot time messages that tell you what it's doing and hide all useful info.

My joy was too early ... the system is now unstable. The first Gnome session after the fix (where I wrote the previous post) was fine, but after reboot the Gnome sessions crash a few seconds after the desktop comes visible. The display generates a red ring (like migraine aura) around the desktop and crashes.

Even my text-mode session where I was looking for the logs crashed after maybe 5 minutes. Will investigate once I'll find time to do the necessary google-ing.

Ok, the nouveau driver behaviour has been erratic. When I powered the system after a bit longer time of system having been off, it booted fine into the Gnome desktop at 1920x1080, and appeared stable although I didn't dare to do anything serious with it. But if I rebooted, or shut the power off and then switched shortly after the power on again, I got the 'migraine aura' and a system crash. Even in text mode, I could get in middle of my work a sudden flow of messages like "Nouveau has stalled at $fffffffff ..."

There may be something wrong with the BIOS, namely there is an error message that flashes by too fast to properly read it

Code: Select all

...[Firmware bug] ACPI region does not cover the entire command/response buffer [mem 0xfed40000-0xfed4807f flags...] 
Updating BIOS might be a good idea, but I seem to recall that ASUS provides BIOS flash updates in a Windows format only (not sure).

I have now blacklisted nouveau by creating an appropriate .conf file in /etc/modprobe.d and running

Code: Select all

dracut -f
Now the command

Code: Select all

lshw -c video
suggests I'm running on i915 driver, and I seem to have 1980x1080 with Gnome at least for 2D. Maybe I'll try the nvidia driver later, but this is good enough for what I intend to use the system for, the Microsemi FPGA tools, without 3D. We'll see how it works. Thanks to everyone for help so far.

For information of anyone interested: upgrading the BIOS to the latest version changed nothing. Even the 'Firmware bug' message persists. The system functions fine under the i915 driver, however.
