After performing an upgrade to my laptop (including a kernel upgrade), I rebooted and found my window manager misbehaving. Let me describe the symptoms:
- Login screen shows up fine
- After logging in, I get a totally black screen with a mouse cursor
- Keyboard shortcuts work (like Ctrl-Alt-T to open a terminal), but opened applications show up in the top-left corner without a border
I rebooted, and got different behavior
- After logging in, I get a background image and desktop icons, but no panel and keyboard shortcuts (such as Ctrl-Alt-T) no longer work. But I can right-click on the desktop and click "Open terminal here".
Rebooting again and logging in then resulted in the black screen.
I tried searching for solutions, and most I found suggested to open a pty and call
startxfce4. These do not help me as windows are able to be launched, just not with borders.
I am not exactly a linux newbie, but I kind of am when dealing with window manager and graphics problems. Any pointers in which log files to review or commands to try would be appreciated.
I also tried looking into reverting my kernel version and it seems that it may be a complicated process because a non-trivial amount of packages depend on the kernel and would also need to be downgraded. I would feel more comfortable going that route with some guidance.
