Furthermore, the new kernel fixes a vestigial 20-year-old workaround that slows down recent AMD processors.
It also marks a start for the operating system's entrance into Arm by introducing support for the Arm-based Qualcomm Snapdragon laptops. Released for most major distros this week, Linux Kernel 6.0 supports the newest hardware architectures, including Raptor Lake, Meteor Lake, Arc Alchemist, and RDNA 3.
The engineers examining the LCD problem didn't say whether the newly-released kernels 6.0 and 6.1 also include fixes for the issue. Most Linux users likely have to wait until kernel 5.19.13 is available for their specific distro. Your laptop might be safe if you can disable Optimus mode. All Nvidia Optimus laptops and possibly some Intel-Radeon combined notebooks could face this issue because they always let the iGPU control the screen, even when the dedicated GPU is rendering the graphics. Greg Kroah-Hartman, the developer who released 5.19.13, said that users should only upgrade to the new kernel if they're experiencing this issue.Īccording to Tom's Hardware, the problem affects any Intel-based laptop that directly wires the integrated display to the integrated graphics. The problem appears to originate from a faulty Intel graphics driver, which Linux kernel engineer Ville Syrjäl describes as a bad panel power sequencing delay. The critical flaw prompted developers to issue a quick update. A Linux engineer found that the issue could ruin the LCD, urging users to immediately roll back to an earlier iteration. Recent reports from Intel laptop users running Linux Kernel 5.19.12 describe "white flashing" on their screens. Versions 6.0 and 6.1 have also begun rolling out with many significant changes.
Fortunately, kernel 5.19.13 has already fixed the issue. PSA: Users running Linux on laptops with Intel processors should avoid Linux Kernel 5.19.12 due to an error that might physically harm the display.
