Bug Description

Binary package hint: xserver-xorg-video-nouveau

Lucid Beta2 (live CD) / Dell Inspiron 1520 / GeForce 8400M GS

After choosing the 'Try Ubuntu without changes on the system', I got for 1-2 seconds a black screen terminal (only the cursor was visible), after that a weird screen and finally sort of a grey screen. I've attached the last two screen images.

It switched between terminals, but the display didn't change at all. For instance, ctrl+alt+f2, "sudo reboot", enter, enter = reboots the system. I found it odd since I thought the terminals didn't use the noveau driver.

"blacklist=vga16fb nouveau.noaccel=1" params didn't work, however the "nouveau.fakeparam=yes" workaround worked.

I've just tried the latest live-cd daily build (16-Apr-2010) and the bug isn't fixed.

I've just tried my luck, installing the RC by using "nouveau.fakeparam=yes". Obviously, the fresh ubuntu didn't work, but I could collect the Xorg.log file. The logs before this were from the live CD with the fakeparam thing.

Hm. So, what appears to be happening here - from your picture - is that nouveau doesn't know how to drive your laptop display. I presume the binary nvidia driver works in this case?

If the binary nvidia driver works, it's likely that an mmio-trace of it correctly initialising the display will be useful for fixing this. You can check out the howto here: https://wiki.ubuntu.com/X/MMIOTracing

Marius Vasilescu (vegancorr) wrote :

Thanks for pointing that out, Chris. I've attached the mmio-trace log.

I've also filled bug #747338 related to this bug, but also to other non-working nouveau cards. Maybe you find the time to have a quick look and review it.

Marius Vasilescu (vegancorr) wrote :

A simple solution to this bug has been posted on nouveau's bug tracker. Maybe it could be included in the final release?

Using one of the two options "nouveau.uscript_lvds=0x0100" or "nouveau.uscript_lvds=0x0300" solves this problem.

The bug has been fixed upstream. I've just did the testing against the latest kernel that has a more recent nouveau version than oneiric and it worked. You can have a look at the upstream bug for more info.

Fixed with the shipping of kernel 3.0 in Oneiric Alpha2.
