I installed Ubuntu 23.04 on two different computers, one with an Intel CPU and the other with an AMD CPU. Both were upgradess from Ubuntu 22.10 (Kinetic) by running do-release-upgrade -d so they weren't fresh installs. Both have Nvidia graphics, and both run xorg rather than Wayland. One is a laptop and the other a desktop computer, and they're having the same two problems:
1. I have Gnome Tweaks installed and have used it to switch the windows control buttons to the left side of windows. This works for Gnome applications, but for third-party applications - Firefox, Solitaire, Eddie (VPN software for AirVPN), etc. - the buttons remain on the right. I have found a way around this: if I reload the desktop by running alt-F2-r, the refreshed desktop then moves the buttons to the left.
2. Not related to problem 1, after either computer runs for a few hours, the Show Apps window shows no apps at all. It's empty. If I run alt-F2-r to restart the desktop, however, after I open Show Apps everything is there. This happens every few hours: I haven't noticed any particular time period, or if it is related only to running certain apps. (This was a problem I noticed on Kinetic, also.) This happens when running Wayland, too, although I can't restart the desktop with alt-F2-r on Wayland; I have to reboot.
Any ideas?
