My guess is that 560 packages lack 32 bit binaries, hence those don’t run.
I’ve compared side by side the packages/dependencies installed by 555 (which work perfectly) and 560 and I get the following packages as suggested:
Which are installed by default with 555.
Unfortunately, when trying to install the same directly one gets the messages along the lines of:
Reading package lists… Done
Building dependency tree… Done
Reading state information… Done
Package libnvidia-gl-560:i386 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
libnvidia-common-560
E: Package ‘libnvidia-gl-560:i386’ has no installation candidate
There’s clearly some packaging issue going on with Ubuntu drivers.
I used an external SSD and installed a live Ubuntu 24 + drivers 560 from scratch, same issues.
Looks like the Ubuntu drivers team have botched this install?
Just for reference, the PPA has done 3 updates to the 560 driver, the 1st one had horrible crashes for most Steam games using Proton, the 2nd one had less crashes but still had crashes compared to 555 which were never happening. The 3rd one basically make google chrome crash segfault. Going back to 555 fixes all steam issues as well making google chrome stable again.
I will wait for 24.10 to test the 560 just in case.
Consider that the 560 driver requires egl-wayland version 1.1.13.1 or higher to properly support EGL Wayland (Release 1.1.13.1 · NVIDIA/egl-wayland · GitHub). In the Ubuntu repository, the latest version for Noble Numbat is 1.1.13, which is before the release of the patch for 560 drivers. You can download and install manually the version 1.1.15 (egl-wayland package : Ubuntu) released for Oracular Oriole (24.10), or wait for an updated version for 24.04 (if it is released at all).
This is the answered. A specific dependency is creating all of these issues. I updated as you suggested and have not had gaming issues nor google chrome crashes. Although I don’t like to mix and match like this.
In my case, after installing the 560 driver and updating egl-wayland, the Google Chrome browser doesn’t work very well. All Graphics Feature are deactivated. When I open the browser, I see the loading animation all the time, and GPU-related errors in the console. Can you show the Graphics Feature Status from chrome://gpu/ for the Nvidia 560 driver under Ubuntu? What is your GPU?
