Based on a report by Phoronix, a brand new Linux kernel – model 5.19.12, is reportedly damaging laptop computer shows. Anybody with a Intel-based laptop computer is in danger, and mustn’t set up Linux kernel 5.19.12.
The difficulty is said to a graphics driver bug that causes undesired energy sequencing delays within the show itself, which may bodily hurt the LCD panels discovered on Intel-based laptops. Based on person studies, the problem causes white flashes to show on display.
This is without doubt one of the only a few occasions we have ever seen a software program replace – not associated to overclocking, have the ability to wreck a pc part bodily. This challenge results all Intel-based notebooks the place the built-in show is wired on to the built-in graphics.
This implies all Nvidia Optimus laptops, and a few potential Intel + Radeon mixed laptops (although we successfully by no means see these) are in danger as properly – because the iGP is driving the first show even whereas the discrete GPU is energetic.
The one exception to this, is that if the pocket book in query can disable Nvidia Optimus totally or the inner show is just not hooked as much as an Intel built-in graphics answer in any respect. Such laptops are uncommon, however they do exist. Fortunately, this solely applies with Intel graphics options, and means all AMD-based notebooks with AMD CPUs or APUs usually are not affected.
The Repair Is Already Right here
Luckily, the Linux group has already launched a brand new kernel that reverts all of the problematic points discovered within the graphics driver again to what they have been in earlier kernel updates.
This new kernel is called 5.19.13, and has already been launched for everybody to make use of. Nonetheless, likelihood is that almost all customers must wait for his or her revered Linux distros to roll out the kernel replace earlier than the mainstream customers get an opportunity to make use of it.
