Bug#996328: xfce: Spurious terminal resize event, stuck size indicator, broken keyboard, right-click, and menu
Package: xfce4
Version: 4.12.5
Severity: important
File: xfce
Dear Maintainer,
While working in Terminal Emulator, I moved the mouse pointer out of
the window. A spurious window resize event occurred, leaving a size
indicator "80x32" on the screen. I minimized the window and the
indicator remained on the desktop. I restored the Terminal window and
the indicator remained. I switched to another Workspace, which seemed
correct, switched back, and the indicator was still there. I tried
typing in the Terminal windows and the keyboard did not work. I was
able to select other Terminal windows. The keyboard still did not
work. I closed the various open windows by clicking the Close
decoration. I right-clicked on the minimized windows in Window
Buttons, but their context menus did not open. I clicked on the
minimized windows in Windows Button and they restored. I closed them
via the Close decoration. I clicked the Application Menu and its menu
did not open. I pressed Ctrl+Alt+Del and the screen went black. After
5~10 seconds, the graphical login screen appeared. I logged in,
opened a terminal, and filed this bug report.
This machine is a Dell Latitude E6520 with an Intel Core i7-2720QM
processor, 16GB memory, 60 GB SSD, and Intel/NVIDIA Optimus graphics.
When I installed Debian 10.8 on it 7+ months ago, YouTube videos
crashed after ~20 minutes. I pulled the system disk and put it on
the shelf. Every few weeks I would install the disk, update/ upgrade,
and test again.
I tried installing the NVIDIA proprietary driver. That was a disaster.
I blame PEBKAC.
After upgrading to 10.9, YouTube videos crashed after a few hours.
After upgrading to 10.0, YouTube videos stopped crashing. I then
started using the machine as a daily driver. Unfortunately, I have
been experiencing desktop malfunctions ever since. Their frequency has
increased recently (I just experienced a spurious desktop select (?)
event when moving the mouse cursor out of a Terminal window). I can
usually get out of them by operating various windows, decorations,
buttons, menus, etc., but not always.
I have tested Debian 10 OS disk in a desktop machine with an Intel
DQ67SW motherbaord, Intel Core i7-2600S processor, and 8 GB memory.
That machine has Intel integrated graphics and has been reliable since
Debian 6 or 7 (~2013?).
Therefore, I suspect the problem is related to the Optimus graphics
and/or nouveau driver.
David
