I opened update manager today and saw i had updates. i applied the updates and they installed without errors. However when I went to play a LEGO starwars game, I get errors. the only thing that's different about my system is these updates. Games worked yesterday don't today. the screenshot shows what changed. I gooled how down grade a flatpak found these directions. https://itsfoss.com/downgrade-flatpak-packages/ but the nvidia drivers aren't listed. where do i go next?

I opened update manager today and saw i had updates. i applied the updates and ...
do you have a timeshift snapshot?
fickle pilot
not sure. where do i look?

Timeshift in your start menu
if you didn't set it up then you don't have them. in that case, I'm not sure. but I'd urge to upgrade to 550 drivers anyway, they're available in driver manager
fickle pilot
I do have a snapshot from yesterday. yes, i have the 550 drivers available. I try them next. so best practice going forward is take snapshot before i upgrade. oh whats a recomended screenshot tool that takes a shot of the active window not the whole screen?

you don't and shouldn't roll back your entire system
the link you posted is quite sufficient if you need to rollback any flatpak
also is LEGO starwars a flatpak or a system package?
since I don't see lego starwars with flatpak search I'm guessing its NOT a flatpak
fickle pilot
I should have said Ill try the drivers first. No, I'm running the windows version in ludis/wine.

changing the flatpak version of the nvidia driver is completely nonsensical
system apps don't rely on flatpaks
if you have updated your nvidia driver (system) not flatpak and not rebooted then the solution is to reboot
fickle pilot
according to the update mansger log in the posted screenshot they were delivered via flatpak. did I read that wrong?
fading pecan
no you just misunderstand how the various things work
the driver loaded by the kernel to talk to your GPU isn't and can't be delivered by flatpak
fickle pilot
reboot time. brb.
fading pecan
the nvidia stuff that IS delivered is libaries that is used by apps to talk to your GPU
the flatpak stuff DOES depend on system libraries to work so if your system stuff is broken badly enough it can make flatpak apps not work
but your system doesn't rely in any way on flatpaks to work so nothing you do in flatpak land will normally in any way effect anything but flatpak apps
in turn apps and runtimes are themselves relatively self contained. A given app may require whatever version of whatever runtimes the developer declared to work correctly but you can have as many different versions of a given runtime as you like in parallel without interfering with each other
so app A can rely on runtime foo version 1 B can rely on 2 and if you install C that requires version 3 no problem you'll just lose a bit more hard drive space storing all 3
fickle pilot
Ok, I'm good. the new driver worked.
fading pecan
notably the runtime for nvidia can be a different version thereof as far as the runtime but if its not the same as your actual driver its not going to work because it wont know how to talk to the driver
so if you have nvidia 550 driver the runtime is going to need to be for 550
ya it was probably just a problem of having a different version running prior to update and everything that was already running works great but new things trying to run a mismatched newer version do not
its basically impractical to load a new GPU driver without killing X and everything underneath it
easiest way to do that is of course to reboot
