Since today I see frequently some weird artifacts showing up on my display, just for a fraction of a second.
I want to make sure that it is not the display which is damaged, so I wanted to choose another kernel version, the one before the latest installed.
On boot process I could not halt the booting to choose a kernel version, like I know it from Ubuntu.
How to do that with Lubuntu?
I tried to hold the shift
key on boot process, but this didn’t show me the advanced options for Lubuntu at the grub bootloader screen.
The current version is
uname -a
Linux MYCOMPUTER 5.15.0-17-generic #17-Ubuntu SMP Thu Jan 13 16:27:23 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
Because everything was OK until yesterday, I assume firstly that maybe one of the updates yesterday are causing the trouble. But I don’t know what was updated yestersday… because this is a development version of Lubuntu, frequently updates are done, sometimes more than once on a single day.
That’s why I assume it would maybe be enough to just choose the kernel version before the current one installed.
It doesn’t make a difference if I choose LXQt or Lubuntu desktop on login, but I prefer LXQt.
I have a mini pc with Intel Celeron J4105
with integrated graphics unit Intel UHD Graphics 600
.
Maybe something is wrong with the graphics drivers in the currently installed kernel version.
I see a message on boot process, don’t know since when this appears, if this maybe is the reason
0.292394 ] x86/cpu: SGX disabled by BIOS.
I also recognize that sometimes the mouse pointer looks not correct, somehow not sharply displayed, the borders look frayed or dotted or so, but after a while OK again.
