Intel-powered laptops are in danger if a Linux replace is utilized, because the pocket book show might be bodily broken.
That is a type of horror situations that PC homeowners dread, after all, and the replace in query is the just lately launched model 5.19.12 of the Linux kernel.
Sadly, a bug within the graphics driver – for built-in Intel GPUs, that is – triggers an influence sequencing problem which, as Phoronix (opens in new tab) studies, manifests as very quick white flashes occurring on the display screen. And as talked about, these can doubtlessly harm the panel, so it is a very critical {hardware} problem brought on by a software program flaw.
As you may think, motion has been shortly taken, and Linux kernel developer Greg Kroah-Hartman promptly launched Linux 5.19.13 the place the defective patches for the Intel graphics driver have been reverted.
Kroah-Hartman famous: “This launch is to resolve a regression on some Intel graphics methods that had issues with 5.19.12. When you shouldn’t have this downside with 5.19.12, there isn’t any have to improve.”
Just some distros are reported as having the problem, having upgraded to kernel 5.19.12, specifically Arch, Fedora, and openSUSE Tumbleweed. Hopefully these distros will present the contemporary launch in a swift method.
Evaluation: A worrying lapse that might be very pricey
Going by consumer studies, some of us with Intel GPUs of their pocket book have been unaffected by model 5.19.12, however others definitely have been hit. Maybe the latter are within the minority, which is likely to be an element as to how this gremlin survived into the secure launch.
It’s a worrying – and uncommon – lapse for Linux, after all, given the attainable gravity of the harm that is likely to be prompted. A ruined laptop computer show is a nasty affliction, and never one thing that’s going to be simple or low-cost to repair.
Even these Intel laptop computer homeowners apparently not experiencing the issue after putting in 5.19.12 must be seeking to improve to five.19.13 anyway, we’d suppose, simply to be protected (who is aware of if the flaw may nonetheless pop up, even when it didn’t initially).
Don’t neglect that this may be a difficulty for these working an Nvidia GPU and Intel CPU with Optimus tech, because it intelligently makes use of each discrete and built-in graphics respectively, that means that with the latter, the terrible flashing display screen may rear its head.
