Linux kernel 5.19.12 can hurt Intel laptop computer LCDs

PSA: Consumers jogging Linux on laptops with Intel processors ought to avoid Linux Kernel 5.19.12 thanks to an error that could bodily hurt the display screen. Thankfully, kernel 5.19.13 has already fastened the issue. Versions 6. and 6.1 have also started rolling out with a lot of considerable variations.

Latest stories from Intel laptop computer consumers working Linux Kernel 5.19.12 describe "white flashing" on their screens. A Linux engineer located that the difficulty could spoil the Liquid crystal display, urging end users to quickly roll back to an previously iteration. The critical flaw prompted builders to issue a speedy update.

The difficulty seems to originate from a defective Intel graphics driver, which Linux kernel engineer Ville Syrjäl describes as a bad panel energy sequencing hold off. Greg Kroah-Hartman, the developer who introduced 5.19.13, said that users need to only update to the new kernel if they're dealing with this concern.

According to Tom's Hardware, the challenge impacts any Intel-dependent laptop computer that straight wires the integrated display screen to the built-in graphics. All Nvidia Optimus laptops and possibly some Intel-Radeon merged notebooks could deal with this problem due to the fact they always enable the iGPU command the screen, even when the committed GPU is rendering the graphics. Your laptop might be harmless if you can disable Optimus mode.

Most Linux consumers possible have to hold out right up until kernel 5.19.13 is offered for their particular distro. The engineers analyzing the Lcd issue failed to say whether or not the newly-produced kernels 6. and 6.1 also incorporate fixes for the challenge.

Launched for most important distros this week, Linux Kernel 6. supports the most recent components architectures, like Raptor Lake, Meteor Lake, Arc Alchemist, and RDNA 3. It also marks a begin for the working system's entrance into Arm by introducing aid for the Arm-based Qualcomm Snapdragon laptops. On top of that, the new kernel fixes a vestigial 20-calendar year-outdated workaround that slows down latest AMD processors.

Kernel 6.1 closes a significant Bluetooth security hole and makes the 1st techniques in the direction of supporting the Rust programming language, which Google uses to build Android. One more addition is a new Mistake Detection and Correction (EDAC) driver that lets Intel systems decode components problems more quickly, even though it is unclear if that contains the Lcd situation. The new EDAC driver error decoder is more quickly than the regular firmware decoder but can even now slide back again to it if required.
