Linux kernel 5.19.12 can harm Intel laptop computer LCDs

PSA: Buyers functioning Linux on laptops with Intel processors really should keep away from Linux Kernel 5.19.12 due to an mistake that might bodily hurt the screen. Fortunately, kernel 5.19.13 has presently preset the challenge. Versions 6. and 6.1 have also started rolling out with numerous significant modifications.

Latest experiences from Intel notebook consumers operating Linux Kernel 5.19.12 describe "white flashing" on their screens. A Linux engineer discovered that the challenge could ruin the Lcd, urging end users to right away roll back to an before iteration. The significant flaw prompted builders to difficulty a swift update.

The difficulty seems to originate from a faulty Intel graphics driver, which Linux kernel engineer Ville Syrjäl describes as a terrible panel electricity sequencing delay. Greg Kroah-Hartman, the developer who released 5.19.13, claimed that buyers must only enhance to the new kernel if they are encountering this concern.

In accordance to Tom's Components, the dilemma affects any Intel-primarily based laptop computer that directly wires the integrated screen to the integrated graphics. All Nvidia Optimus laptops and perhaps some Intel-Radeon blended notebooks could face this difficulty for the reason that they generally allow the iGPU handle the monitor, even when the focused GPU is rendering the graphics. Your laptop computer could be protected if you can disable Optimus mode.

Most Linux users very likely have to wait around till kernel 5.19.13 is offered for their distinct distro. The engineers examining the Lcd problem failed to say regardless of whether the freshly-released kernels 6. and 6.1 also include fixes for the difficulty.

Released for most significant distros this week, Linux Kernel 6. supports the latest hardware architectures, such as Raptor Lake, Meteor Lake, Arc Alchemist, and RDNA 3. It also marks a start off for the working system's entrance into Arm by introducing assist for the Arm-centered Qualcomm Snapdragon laptops. Moreover, the new kernel fixes a vestigial 20-calendar year-old workaround that slows down the latest AMD processors.

Kernel 6.1 closes a important Bluetooth safety gap and can make the first ways in the direction of supporting the Rust programming language, which Google works by using to create Android. Another addition is a new Error Detection and Correction (EDAC) driver that lets Intel devices decode components faults quicker, nevertheless it can be unclear if that involves the Lcd difficulty. The new EDAC driver mistake decoder is a lot quicker than the conventional firmware decoder but can still drop back again to it if required.
