Description Loïc Herry 2014-09-17 00:59:39 UTC
Created attachment 106398 [details] Screen corruption Boots and login fine, then as I open a terminal, there will be some screen corruption. As I open more windows (firefox) and loads pages the screen gets worse and worse up till X crashes (can still move the mouse). I've built the newest linux kernel with the nouveau git (kernel 3.17 rc2+), also had the problem with stock ubuntu14.04 and with a 3.16 kernel. The card is an Apple Nvidia Geforce 320M. It doesn't have dedicated memory, it uses 256MB from the system ram. I include the logs, in the syslog, you will see many boots most of them in 3.16 but one in 3.17 at the end. Let me know if I can give you anymore info/logs/trace. Thanks

kern.log http://www.aiklos.com/kern.log It's huge, will try to post a more up to date (with the 3.17 log) later.

This seems like an extremely unlikely thing to help, but could you try booting with nouveau.config=PCE0=1 This should force-enable the copy engine (which is being disabled because we see bits that we think mean it should be disabled). I suspect things will be even worse with that, but... worth a shot, I suppose?

I'm booting in EFI with grub.

Created attachment 106504 [details] [review] PFB patch I wonder if this patch could yield some improvements, as your chipset is not too far away from mine (MCP79: NVAC) and I had kind of similar problems at some point.
Comment 7 Loïc Herry 2014-09-24 16:50:26 UTC
Hi, unfortunately no. There was no improvements with the patch. I compiled with the 3.17 kernel from freedesktop git & the drm-next branch, Added the patch. With 3.17 the loading screen is affected so I can't even login. Ideas or pointers welcome. Thanks

Hello Loïc, I tested Nouveau on a friend's laptop (an MBP with an MCP89 as well), and I don't recall seeing any screen corruption as he used it and played some games. It was with kernel ~4.1 IIRC. Are you still experiencing this issue with kernel 4.3 or 4.4? Sorry for not coming back earlier…
