reported that phonics, New Linux Kernel – Version 5.19.12 Reported to Damage Laptop Displays. People with Intel-based laptops should not install Linux kernel 5.19.12 as they are at risk.
This issue is related to a graphics driver bug that causes unwanted power sequence delays in the display itself, which can physically damage the LCD panel found in Intel-based laptops. According to user reports, this issue causes a white flash to appear on the screen.
This is one of the few examples we’ve seen of a software update that has the power to physically damage a computer’s components, unrelated to overclocking. This issue affects all Intel-based notebooks where the integrated display is wired directly to the integrated graphics.
This means that all Nvidia Optimus laptops, and possibly some laptops with an Intel + Radeon combination (although you virtually never see them) are also at risk. increase.
The only exceptions to this are if the notebook in question can disable Nvidia Optimus entirely, or if the internal display is not connected to the Intel integrated graphics solution at all. Such laptops are rare, but they do exist. Thankfully, this only applies to Intel graphics solutions and all AMD based notebooks with AMD CPUs or APUs are unaffected.
the fix is already here
Fortunately, the Linux community has already released a new kernel that reverts all problematic issues found in graphics drivers to the state of previous kernel updates.
This new kernel is known as 5.19.13 and has already been released for everyone to use. However, most users will likely have to wait for a respected Linux distribution to roll out a kernel update before mainstream users have a chance to use it.
