I use the same computer since version 4.0
No hardware changes.
I reinstalled Qubes with the latest version, 4.1 in May.
Since then, many problems, like :
- Random freeze of firefox and chrome, on Fedora and Debian.
- No more screen on the laptop (see photo report here )
- Battery out of order
- Impossible to resize “Files 3.38.x” on Debian and “Files 41.5” on Fedora. No problem for the different programs (libreoffice, audacity, digikam, calibre…) nor for thunar in dom0
- non-exhaustive list…
Many of these problems are listed here and the culprit would be i915. But why, for me, only on 4.1, when QubesOS was running like clockwork with 4.0 ?
Questions:
- I’m looking for what parameter to add in /etc/modprobe.d/i915.conf that could, already, improve the display problem?
I have tried :
options i915 enable_rpc=1 (without success)
then :
options i915 enable_fbc=1 (it worked once and since this morning again white screen on the laptop) (I just realized that the parameter is back to its initial value -1 ? )
I’m looking in vain for a doc of the i915 module with the different options and their uses. Not a fan of testing them all one by one.
Here is some material if you have ideas to help me:
