Numerous bugs
by slkw from LinuxQuestions.org on (#4XB5K)
In the event that someone in the Debian project wants to fix some bugs, here are a few I've encountered. I was initially using Buster on a 2015 Macbook Pro with the sddm display manager, then I switched to xfce.
0. Mounting an encrypted drive from Dolphin results in numerous notification popups on the lower right-hand side complaining about File Not Found.
1. If the disk gets full, graphical login (sddm) no longer works.
2. If the disk gets full, no GUI warning appears to draw attention to this fact.
3. Switching from sddm to launching X from the command-line and using xfce4, a number of bugs appeared:
- Keyboard brightness up/down keys don't work and cause the backlight to turn off. If I then close the lid and reopen it, the backlight flickers on for maybe 1/4 second and then switches off again.
- Xfce4 menu's lock screen feature does not work.
- Closing the lid of the laptop does not cause sleep.
- Audio volume up/down keys don't work.
4. Wifi connection is often permanently disabled after suspend to RAM, requiring a reboot.
5. Sometimes screen brightness goes higher/lower on its own even though webcam area is covered up.
6. Sometimes after logging in after suspended, the xfce panels all become totally unresponsive.
