My GPU situation is definitely not resolved. I can't get it to switch to the discrete 90% of the time. and then when I do, I cant get it to swap seamlessly between intel for desktop and radeon for games. So my laptop is delegated to being a terminal and browser only machine.
Also, since 4.2, I can't change the screen brightness. I can change it during the BIOS splash, but once the kernel takes over, the key stops doing anything. The brightness slider moves around, but doesnt actually do anything.
It's a shame too, gaming is the one thing keeping my dad (who has the same laptop) from switching over to linux.
- guitarbill 10y agoCan confirm on W520, W530, and W541 (I think). They all have terrible GPU support. The W530 for example has no video out muxer, so you have to use discrete graphics if you want any kind of external display, tanking your battery life. Brightness doesn't work. Not only that, the W520, T420, and L420 [0][1] and W530 have BIOS/chipset bugs that mean you need to disable x2apic. Avoid unless you love tinkering with Linux.
