Screen resolution after update

**loutchoa** · November 19th, 2020

Hi everyone,

I just ran an update to Ubuntu 18.04, and now I can only access a 1920x1080 resolution for my external monitor.
It was 2540x1440 before the update. I guess some Nvidia stuffs was the source of the problem, but I am definitely not expert in these things.

Cheers,
François

Which GPU? Is it still supported?

I'm using v430 on my 16.04 desktop with a 1030 GPU.

Code:

$ dpkg -l|grep nvid
ii  nvidia-430      430.64-0ubuntu0~gpu16.04.6     amd64    NVIDIA binary driver - version 430.64

Is the nvidia driver actually loaded and being used?
To check that:

Code:

$ lsmod |grep nvid
nvidia_uvm            819200  0
nvidia_drm             45056  2
nvidia_modeset       1114112  3 nvidia_drm
nvidia              19046400  84 nvidia_uvm,nvidia_modeset
drm_kms_helper        172032  1 nvidia_drm
drm                   401408  5 drm_kms_helper,nvidia_drm
ipmi_msghandler        53248  2 ipmi_devintf,nvidia

To get the correct driver,

Code:

sudo ubuntu-drivers autoinstall

should handle it for nvidia with Ubuntu LTS releases.

If a GPU driver gets changed, a reboot of the OS is required so the OS can load it.

BTW, whenever posting output from a terminal, please, please, please, use code tags.
https://ubuntuforums.org/misc.php?do=bbcode#code explains how.

I too had a strange behaviour after a reboot for update.
no more GUI only text console.
The solution was to reboot the HDMI TV I use as monitor.

Strangely, on a much higher resolution at home,
no problem, but here at work, still.

Code:

$ sudo ubuntu-drivers autoinstall

Anyways, here are the outputs of dpkg and lsmod

You have a mix of different Nvidia drivers versions.
That is always bad but if it works do not touch it for the moment.
If it breaks then purge all Nvidia drivers and install only the recommended version for your card.

Code:

ii  nvidia-driver-435
ii  nvidia-driver-455

Plus there are i915 drivers for the Intel GPU.

As said above, I'd remove all the nvidia drivers

Code:

sudo apt-get remove --purge nvidia*

reboot
then install the recommended one (1) using ubuntu-drivers. After that, rebooting again will probably be needed.

Note that I used 'apt-get', not 'apt' for the purge. apt-get supports wildcards which apt does not.

After the first reboot, a GUI may not happen. Don't worry. Just login (may need to change to a different console (use <cntl>-<alt>-F1 or F3 or F6 ... to find alternate consoles) and run the ubuntu-driver tool

Back to university, and no real change. Maybe I did something wrong?

After I ran sudo apt-get remove --purge nvidia* and and sudo ubuntu-drivers autoinstall,
the result of dpkg and lsmod

Code:

$ dpkg -l | grep nvid

And still unable to change the resolution of my monitor to 2560x1440. Actually not completely true. I tried to change it using nvidia-settings. Kind of work but the result looks terrible.
I also played with gtf and xrandr, not sure I understand how it works. Resolution and rate are from Lenovo's (ThinkVision 20-27 2540x1440)

Code:

$ gtf 2560 1440 60

  # 2560x1440 @ 60.00 Hz (GTF) hsync: 89.40 kHz; pclk: 311.83 MHz

$ xrandr --newmode "2560x1440_60.00"  311.83  2560 2744 3024 3488  1440 1441 1444 1490  -HSync +Vsync
$ xrandr --addmode DP-5 "2560x1440_60.00"
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  18 (RRAddOutputMode)

Completely stuck...
Any help greatly appreciated

With the local lockdown, I probably won't need a solution before the new year, but still... Maybe someone could point to Any better location where I could ask?
