Alright, I think I may have found my solution.

• The crash only occurs on desktop environments that use x11, it does not occur on DEs that use Wayland.
• The only DE that uses Wayland that Pop officially supports (that I can tell at least) is “Pop (on Wayland),” which is GNOME.
• GNOME doesn’t look or feel familiar to me, Cinnamon does. I really like Cinnamon. But today I realized GNOME extensions can be used to make GNOME feel different, and are (at least so far) remarkably stable.
• By installing the extension manager, and then adding the extensions “Dash to Panel” and “ArcMenu” and tweaking them I’ve been able to achieve the look and feel that I was going for with Cinnamon, on a DE that doesn’t crash on suspend. (Note for anyone else that tries this: I had to disable the “Cosmic Dock” and “Pop COSMIC” extensions so things would play nice with the new extensions.)

So it’s a workaround. It’s essentially finding a way to make the “new” stuff feel like the old stuff, but as an added benefit, I get all the functionality that the new stuff offers.

So after installing it I see: nvidia-driver-550 is already the newest version (560.35.03-1pop0~1729800494~22.04~4a3cad6)

So 550 is there, but it’s using 560. I assume that means I need to purge all traces of 560 and 550 and then reinstall 550, unless I can specify somewhere to use 550.

However in software and updates there is no 550, only 560.

This is getting deep and complicated.

So I tried using the command in the snippet, and made sure that CC was capitalized, but the error log still says “You are using: cc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0”

Going to the post that talks about changing your version of GCC it looks like my gcc might be pointing to the “11.4.0 cc”?

But when I run: sudo apt-get install gcc-4.3 gcc-4.4 g+±4.3 g+±4.4

I can’t find those packages. And when I run:

sudo update-alternatives --remove-all gcc sudo update-alternatives --remove-all g++

I find no alternatives. Sheesh. When I go this many layers deep I get worried that I’m going to potentially break something that will make bugtesting for other future things harder.

Finally got around to this. I tried installing while logged in, then realized I should Ctrl+Alt+F2 (or something) and stop gdm before installing.

I got an error message, there was an error while building kernel modules. Checking /var/log/nvidia-installer.log I think this is the culprit:

warning: the compiler differs from the one used to build the kernel The kernel was built by: x86_64-linux-gnu-gcc-12 (Ubuntu 12.3.0-1ubuntu1~22.04) 12.3.0 You are using: cc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0

does not match the compiler used here:

To skip the test and silence this warning message, set the IGNORE_CC_MISMATCH environment variable to “1”. However, mixing compiler versions between the kernel and kernel modules can result in subtle bugs that are difficult to diagnose.

So I’m using 11.4.0 instead of 12.3.0? Not sure what that number is. Both kernels are based on Ubuntu 22.04. I’m starting to think if I really want cinnamon I should use a distro that was made for cinnamon, like Mint.

Hey thank you! I’ll give this a shot tomorrow. I think my install uses GDM, not light-dm? I have Cinnamon but not Cinnamon Wayland in my list.

But I’ll try the 550 drivers for sure!

Ok, so switching to Pop on Wayland works. I didn’t mention this in my original post, but I’ve been running Pop on Cinnamon. So I either need to get comfortable with Pop’s DE or figure out if this is a cinnamon issue.

Previously I had an issue with fullscreen games having weird lag issues on Wayland. Though… testing that out now, that seems to no longer be an issue.

After trying this for a few minutes, I really don’t like how slow the dock shows itself when I hover near the bottom of the screen, and i don’t like how the application bar adds visual noise to the top of the screen. To me, it makes more sense for the two bars to be united as one like in cinnamon. :/

Out of curiosity, I wonder if the crash occurs when I’m in Pop x11, or if this is a cinnamon-specific bug.

EDIT: The crash occurs on Pop’s default DE on X11, and cinnamon on X11, but not Pop on Wayland.

Oh man, so Pop!_OS has a “pop shop” where it officially supports 470 and 560. 550 isn’t on there so, while I could try it, I wouldn’t expect it to work.

In “Software and Updates” I have options for the “NVIDIA driver metapackages” for 390, 470, and 560. 560 is currently selected. I also have the NVIDIA server driver metapackage for 535, so I could try that. It would be newer than 470 but not as current as 560.

But since the chances this would fix it are already low (and 560 drivers fixed my other issues), I’m hesitant to try unless I exhaust every other option.

Do you mean switching from x11 to wayland?

For me personally, any game in the Super Smash Bros series.

They’ve always been a go-to when hanging out with friends, in their time.

Melee still has a following. Nobody likes brawl because of tripping (among other things i’m sure), but I learned how to mod brawl and added so many custom stages and character skins. Sm4sh was ok, and Ultimate is so complete.

Yeah it’s Nintendo and “it’s always moral to pirate Nintendo games” and there’s plenty to complain about their online services but I’ve played smash so much that every time a new game comes out immediately a must-buy.

Great game! (Also happy cake day)

What are your favorite games to play?

I used to love president as a kid, now I play it a lot in clubhouse games on the switch. I know a few friends who play spades.

Oh man, I can’t figure out what I did.

Somehow I routed the main display to the RDP session, meaning if I plug in a monitor I get a black screen instead of the desktop. I have to figure out what file I edited to do that. But searching online now none of the tutorials use whatever method I used roughly 6 years ago.

Oof. This is rough. What config files are you referring to?

I’ll give that a try.

Back when I set this up, for some reason, to get RDP working I needed to disable the local video output and have the main desktop be funneled into the remote session. I don’t remember the details of how or why. I’ll figure out how to reverse it and log in locally and see what I can gather.

This machine has always been GNOME. I ran “sudo do-release-upgrade.” I didn’t specify any flags for XFCE. I’m going to try to log in locally and see how it looks there.

It’s using RDP. I’m going to check out how RDP is configured on the machine and see if I can set it up “fresh” again. I think I went with RDP instead of VNC because I was connecting to it with a windows machine in the past and using RDP meant I could use the native windows RDP client.

Now that my primary machine is running Pop!_OS, I can check out whichever protocol has the better connection and re-set thing up with it.

I didn’t have an issue like this going from bionic beaver to focal fossa, but I don’t think my setup was as complicated before. Do other distros have this problem? Mint? Debian? (Does Debian ever update?)

That makes a lot of sense. I’ll work on logging into the machine locally and see what I can figure out from there. Thanks!

Totally fair. This machine has just been long running and switching distros has been more work than it’s worth. Though because things are breaking I’m looking to alternatives now. But for the time being, and to help me figure out this problem if I have it in the future, I’m trying to figure this out.

Yeah I’ve been running this machine on ubuntu since Bionic Beaver in 2018. Cannonical wasn’t such a bad guy back then, and migrating everything over to a new distro has always taken more effort than it’s worth. This machine runs headless and for the most part I interact with it though portainer so it hasn’t been an issue.

It’s just with the occasional remote desktop login that things are broken now. Do you have a recommended distro for servers/remote desktop usage?

The problem is that some desktop elements/settings seem to be xfce while some others are gnome. I’m going to need to do a deep dive to figure out how I set up remote desktop on that machine. Log in locally, get it working locally correctly, then see if I can get it working over RDP correctly.
