do-release-upgrade 18/04 to 20.04 corrupted video issue

[rsteinmetz70112]

I ran a do-release-upgrade on an 18.04 computer. It ran and produced no errors. However upon rebooting I get a corrupted image on the monitor after logging in. It worked just fine in 18.04.

Which (x)Ubuntu? My crystal ball is broken.

Your NVidia Geforce 7025 is using the opensource Nouveau driver... which covers that GPU... You also have 3rd Party, Proprietary drivers available.

What do you mean, when you are saying that it is now getting a corrupted image? Could you descript that, upload a screenshot or a picture of as an attachment?

[rsteinmetz70112]

I am using Ubuntu 20.04
The screen shot doesn't give the full effect because it changes as the mouse moves over the screen.

I thought the Nvidia proprietary drivers for the chipset had been discontinued.

NVidia Driver 304 supports that card (probably one of the last that did.

The easiest way, in a terminal session:

sudo apt install -y ubuntu-drivers-common
ubuntu-drivers list

Inside of the ubuntu-drivers package is a utility called nvidia=detecter which in that last command, it uses this utility to query your GPU, then devides if there is an appropriate driver in the 3rd Party Repo's. If it comes up with matches, it will list those driver package names... So please post the output of that last command...

If it does come up with package names, then do

sudo ubuntu-drivers autoinstall

It will then pick out the best choice of those drivers and install it.

OR_ You could decide to install one of the packages listed via APT.

sudo apt install <package_name>

IF there is no drivers listed, tell me, as I know that the package for NVidia Driver 304 is still in the Ubuntu Drivers Team PPA.

[rsteinmetz70112]

# ubuntu-drivers install
No drivers found for installation.

I understand that the Nvidia 304 driver is not compatible with current kernels.
I don't understand why the nouveau driver worked with 18.04 but not 20.04

I looked at this ppa, https://launchpad.net/~graphics-driv...ive/ubuntu/ppa and it doesn't appear to have a version of the 304 for 20.04 - it looks like the last version is for 18.04

[MAFoElffen]

In that case... The NVidia Driver Version 304 is in the Ubuntu Drivers Team PPA...

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
sudo apt install -y nvidia-graphics-drivers-304

You didn't say which kernel option you were using when using bionic or 18.04. If it was the GA kernel (4.15), then you'd notice a big change when upgrading to focal, however may have noticed no change if you were using HWE on bionic (18.04; 5.4) and upgraded to focal (20.04; 5.4) using GA.

This reminds me of a recent bug report reply from Daniel Van Vugt (vanvugt) on QA-testing issues on impish where my old nvidia card has bugs in nouveau that are unlikely to be fixed (impacting GNOME & KDE), where the suggestion was to return the box to focal or 20.04 & use the older GA kernel. If you're using an HWE kernel; I'd suggest trying the GA kernel.

My other thought - I have no graphic issues at all on that box I'm referring to with other desktops, ie. I'm involved with the Lubuntu team so the box is mostly used for Lubuntu testing and I don't recall every having a video glitch with that Lubuntu (nor with Xubuntu; only Kubuntu & Ubuntu (GNOME) have issues that I recall). ie. if you're not tied to GNOME/KDE, switching to another DE may also be an option.

Note: I'm no expert with graphics - I ignore it unless it's a problem

Well a way to check would be for him to do

uname -r

...and see if it is HWE or Generic... Now you have me curious about that.

[rsteinmetz70112]

As I thought after adding the ppa, no drivers were found

# apt install nvidia-graphics-drivers-304
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package nvidia-graphics-drivers-304

I am using the generic kernel, not the HWE

# uname -r
5.4.0-80-generic
