Xorg.0.log

Got a Lenovo T530 notebook with a NVS 5400M card.
Suspending to RAM and resume from console only does work fine.

But doing it from X i've get a broken X system, starting X after the resume
basic stuff from mdm display manager is ok, but as soon as cinnamon is starting
its broken again.

Attached is the Xorg.0.log with errors logged.

dmesg is also there - the first 2 errors with cinnamon were logged when i did
"service mdm stop", the other 4 were logged after "kill -9
7350".
Only a reboot did work and it was possible to reboot the box.
Attached is also a full backtrace from gdb after X was tried to shut down via
"kill -9" which did not work.

Its a stock ubuntu 13.10 with mesa 9.2.1.

Can you see if applying
http://cgit.freedesktop.org/nouveau/linux-2.6/commit/?id=968a8d1b6c32c9f466f236032770b9165ece045a
helps at all? (Or just run the nouveau/master kernel.)

Its a little bit better - X is coming back from resume but things does still
not work.
Stopping X does work and i can restart X once - but after login to cinnamon it
hangs again, logs are attached.

I'm not convinced that there have been changes which would fix this in the
past
~2 years, but I highly recommend trying a more recent kernel and seeing if this
persists. The driver's been rewritten ~twice since 3.11 (if you go directly
for
4.3-rc), we've fixed a lot of ctxsw issues, and probably a host of other
things.

Hi,

i did what you've suggested and used 4.3.0-040300rc1-generic #201509160642
SMP
build from ubuntu mainline ppa.
And i am really happy - did S3 twice and all works fine, its waking up and
works - i can even do S3 twice, resume and it works. Even KernelModeSetting on
console does work flawlessly now where 3.13 did work and 3.16 did not with my
external monitors, thumbs up - seems fixed with 4.3-rc1.
