Cannot change default screen resolution in Arch

kkoistinen · 02-09-2021, 01:50 PM

Hello everyone,

Here's the problem: I recently bought LG's FullHD Monitor/TV. I am using Arch Linux with NVIDIA Corporation GF119 [GeForce GT 610] display adapter. (Adapter type acquired from lspci). Hardware is HP Pavillion, quite old version. Original monitor can display 1600xsomething.

When I switched to this monitor Arch somehow detected default screen resolution at start and limited maximum resolution to 1024x768. I have tried original monitor after that and it can still manage 1600xsomething.

xrandr gives the following:

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1024 x 768, maximum 1024 x 768

1024x768 0.00*
800x600 0.00
640x480 0.00

lspci gives the following:

How can I change default resolution to Full HD? LG's specs in Internet mention possibility of 1920x1980.

You need to load correct driver for it, otherwise it will fall back to a generic driver, this is what is happening right now. Follow your distro Wiki, all distros have articles about Xorg configuration.

mrmazda · 02-10-2021, 02:30 AM

Far more often than not, in any mainstream distro from the past decade, X will automagically configure on the fly. When X fails, Xorg.0.log in /var/log/ should be inspected for errors that constitute clues to what is wrong. If Xorg.0.log is absent in /var/log/, look for /var/log/Xorg.1.log, and for Xorg.0.log in ~/.local/share/xorg/, if you find them all, the one with the most recent timestamp should be inspected. If you need help understanding what it contains, upload it to http://paste.debian.net/ this way:

Code:

pastebinit /var/log/Xorg.0.log

Provide the resulting URL and someone here should be able to interpret it. Of course, only upload the appropriate instance if you found more than one.

The following should roughly match your PC's X, once things are working as they should:

Note there are two drivers listed in inxi output. The first is the kernel's device driver, in this case named nouveau, specific to NVidia GPUs. Kernel device drivers are provided with each specific kernel.

The second driver listed is the Xorg DDX driver, named Modesetting. All the competent FOSS Xorg DDX drivers depend on Kernel Mode-Setting from the kernel driver. The Modesetting DDX is the upstream default DDX for all non-ancient AMD/ATI, Intel and NVidia GPUs. An optional/alternate DDX for your 610 is named Nouveau, an older, and reverse-engineered technology. If anything prevents the kernel's Nouveau driver, as in the lsmod output above, from loading, no competent DDX driver will load, and one of two crude fallback drivers, FBDEV or VESA, will usually be employed, with a common result being what you're experiencing, resolution limited to 1024x768. Xorg.0.log will report which DDX is in use.

Another alternate Xorg driver for your 610 would be a legacy version of proprietary NVidia drivers. Special instructions for their installation and use are normally provided with them.

Yours is a somewhat unusual situation. It's common for motherboards with MCP61 chipsets to produce trouble with graphics device selection, unlike most others that automatically prefer the add-in GPU to the onboard IGP (GPU). You may need to change a BIOS setting to engage the 610 GPU instead of the onboard. You might also need to update the motherboard BIOS to make the 610 preferred.

So, check your BIOS, then let us have a look at Xorg.0.log, and inxi and lsmod output. The latter two should be copied and pasted here surrounding them with code tags.

Hi,

and thank you all for helping me out with this one. For starters some information about my computer. It is an old HP Pavillion with default/recommended screen resolution of 1600x1020. When I start Linux (my distro is Arch) with old monitor it switches nicely to 1600x1020. Anyway here is link to Xorg.0.log:

I couldn't get inxi running (command not found). However lsmod is as follows

My guess is that this new monitor doesn't recognize HP's recommended screen resolution and therefore it changes to lower. This recommended resolution pops up once I turn computer on.

I will post more information if required. BIOS isn't configured to onboard and is as PCI with options for PCI-16 and PCI-1. I tried all options but nothing helped with this problem.

Yours

That's hardly correct. Screen resolutions are 16:9 (e.g. 1600x900) or in older stuff, 4:3 as in 1600x1200.
So X will hardly have a mode for 1600x1020. Try 1600x900. Let us know how it looks. I don't think 4:3 monitors went as high res as 1600x1200. The biggest they went was 1280x960, iirc.

Emerson · 02-11-2021, 07:34 AM

Log shows what I suspected, Xorg is falling back to VESA.

Code:

(EE) open /dev/dri/card0: No such file or directory

And this is the reason, kernel driver for your graphics card is not loaded and as a result Xorg cannot use correct driver, using generic VESA instead.

Most distros provide inxi by default. You can get it here.

The error message in Xorg.0.log (EE) open /dev/dri/card0: No such file or directory is fatal to competent FOSS Xorg DDX driver operation. The modesetting DDX driver loads, but cannot be used. Thus, Xorg falls back on the VESA driver, which does not support your display's native resolution.

Did you build your own kernel? lsmod output shows the nouveau kernel driver did not load. This will cause absence of /dev/dri/card0. If you build your own kernel, you must make sure nouveau is either built-in or built as a loadable module.

The nouveau kernel driver also may not load because it has been blacklisted, an occurrence typical of an installation of one of NVidia's proprietary graphics drivers. It can remain so even after uninstallation if uninstallation instructions are not followed to the letter.

Other resolutions I recall using include1856x1392, 1800x1350 and 1792x1344.

I see. I don't claim Ireland was at the cutting edge here. We're pretty well there now. In any case, he was using a 1600x1020 resolution that was neither 4:3 or 16:9, and as you pointed out, using a (4:3)vesa driver.

The error message in Xorg.0.log (EE) open /dev/dri/card0: No such file or directory is fatal to competent FOSS Xorg DDX driver operation. The modesetting DDX driver loads, but cannot be used. Thus, Xorg falls back on the VESA driver, which does not support your display's native resolution.

Thank you for helping me out with this one. So what should I do? I have tried pacman -S nvidia but that doesn't change things.

Check out why kernel driver is defunct and fix it, of course.

Ok I'll see what I can do. Apparently nVidia driver is corrupted.

Well, the Xorg log has expired in pastebin by now, I do not recall seeing any nvidia driver load attempt there, but I may not remember correctly. You are very different person, for me it is a matter of minutes, check Xorg log, see the problem, check dmesg, see the problem, fix it. You seem to have all the time in the world, it has been days now.
