Login screen glitch lightdm on newer than kernel 5.4

Support Graphics & Display
, , ,
1

Hi when I use kernel 5.4 all is ok. But everything after that kernel I get very bad login glitching (see image).
After I log in everything is ok. Even after I use ctrl+alt+f1 and then go back. After I close lid and it goes to sleep and then it repairs itself on wake.
I tried tearfree option in xorg
/etc/X11/xorg.conf.d/20-intel.conf

Section "Device"
        Identifier "Intel Graphics"
        Driver "intel"
        Option "TripleBuffer" "true"
        Option "TearFree" "true"
EndSection

It didn’t helped. Can someone please help me with other than “Just use 5.4”. I’m using lightdm, xfwm4 and xfce4 Thanks

added

Option “AccelMethod” “uxa”

but whole system is now laggy so that’s not solution

Hi, i am having the same kind of issue.
For now the best i found is :

  • log in ,
  • change the display frequency from 60.0 Hz to 59.9Hz :
    • hit windows key, then type “dipslay” then enter
    • guess where th refresh rate is and change it to 59.9 Hz
    • guess the apply button
    • some fiddling on advanced to automatically setup display

then logging is still dirty but it gets better afterwards.

i disabled the quiet option in boot : at first the text display is right but then it starts scrambling (not sure if using the proper verb here)

snippet of grub config :

GRUB_TIMEOUT=5
GRUB_TIMEOUT_STYLE=hidden

Good old archiwiki on intel graphics wiki (i tried so post a link but i could not) and search for 620 i tried it but no change
