Just got a new laptop and wanted to install Linux on it. Currently has win11 and all works ok (so i know the hardware is ok). Whenever I live boot to any live usb (fedora, manjaro, arcolinux, endeavour tested so far) the graphics glitches terribly and it’s even worse when moving the cursor. Screen tears, flickering random colours, completely black
I see some information about disabling PSR in the kernel but all the information seems you have to do this with the os already installed.
i do have a video which may help, if i can post here?
Hi megavolt,
Thanks for all the info. I’ve seen a few bits like this (editing the kernel), but cannot see how to do it from a live usb or windows environment?
Last time I edited the grub file and saved it, I tried to run update-grub but the package was not found (cannot remember the exact error message)
added intel_idle.max_cstate=1 i915.enable_dc=0 i915.enable_fbc=0 to GRUB_CMDLINE_LINUX_DEFAULT= and tried sudo update-grub but get error
/usr/bin/grub-probe: error: failed to get canonical path of ‘overlay’.
any help appreciated
megavolt, thanks so much for this.
scrolled down to the boot option, edit the grub menu, added the psr=0 option then ctrl-x to boot, no graphics glitching at all,

I’ve also got a Lenovo Ice Lake, but not touch screen; had trouble with the trackpad that was a precipitated by a kernel issue. I had to edit kernel parameters to blacklist the elants_i2c module.
But yea, good that you’re doing an install. You’ll get the glitches ironed out, I’m sure.
Will try given suggestions.
Have EliteBook G3 with intel graphics and same problems… Think they began from kernel 5.14 or even earlier one… A lot of workarounds to try to solve the problem, but can’t understand why these patches are not included in the kernel… Downloaded latest xfce edition, but getting frozen screen with washed colors and need to do hard shutdown.
