ACPI error messages on Lenovo W540

Hello, I'm trying to set up on a lenovo W540 mobile workstation I recently purchased. Things work well for the most part (including suspend/resume), however there's some error messages that I suspect are at the root of why the nvidia Xorg driver doesn't work, and possibly also at the root

Re: ACPI error messages on Lenovo W540

Yes it does. The messages may not be related at all; it's just a suspicion. I am more certain, however, that there's an issue preventing the nvidia driver from working. On Jun 17, 2014, at 10:16 AM, Hans Petter Selasky h...@selasky.org wrote: On 06/17/14 15:54, Eric McCorkle wrote: I

ACPI debug messages

Hello, I decided to try tracing through the evaluation of the DSM method in order to track down where the graphics driver failure I mentioned earlier is coming from. However, it looks like there's already an extensive debug logging system in place in the acpica system. Can this be

Lenovo W540 blank screen on suspend/resume after update

Hello, I updated my kernel and userland with a fresh update from 11 yesterday, and I'm now seeing a blank screen after suspend/resume, where it was working fine previously. I had been trying out the new vt console, so I switched back to sc, but the blank screen is still there. Sorry, I

Attempting to diagnose suspend/resume issue

A long while ago, I reported my screen not coming back on after resume, shortly after r274386 went in. Unfortunately, the follow-on patch didn't seem to work for me. (r274386 changed the way devices get powered down/up, and r274397 fixed a typo in r274386 that tried to power down/up the wrong

Hello everyone, It seems I'm plagued by blank screens on resume again on a different laptop... *sigh* I've done quite a bit of diagnostic work on this, and there seem to be some clues, but I'm a bit stumped at this point. The following github repo has patches that add extra logging, which

Hello everyone, I'm looking into what it would take to add support for various bits of functionality on my platform (Purism's Librem laptops). Specific things I'm looking to do are the following: * Screen brightness support (the brightness sysctls don't currently do anything when changed) * If
