Description Jeremy Huddleston Sequoia 2015-11-20 01:18:14 UTC
I updated my Samsung Chromebook to Ubuntu 14.04 and ran into an issue described on Ubuntu's bug tracker at https://launchpad.net/ubuntu/+source/xf86-video-armsoc

The system is perfectly usable using fbdev, but if I switch to using armsoc, I run into issues.  Upon starting the X server, I see my mouse pointer on screen.  About 4 seconds later, the lightdm login screen appears.  About 3 seconds after that, the login screen disappears, and only the mouse pointer remains on screen.

dmesg is filled with '[drm:fimd_win_mode_set] *ERROR* Invalid panel parameters' messages

I am experiencing this issue with the version packaged with Ubuntu (0.6.0) as well as current git (ee9f1d96193d4fc2887183b613f209b18a93e718, 1.4.0).

$ uname -a
Linux localhost.localdomain 3.4.0-5-chromebook #5-Ubuntu SMP Wed Feb 20 14:59:17 UTC 2013 armv7l armv7l armv7l GNU/Linux

I messed up the copy of the downstream bug URL.  It should have been:

We're struggling to reproduce this issue - could you please provide some more information about your setup?

In particular:
- Which Mali userspace driver version are you using? You can find this out by looking at the name of the /usr/lib/arm-linux-gnueabihf/mali-t62x_* directory.
- Are you running Ubuntu in a chroot or natively?

- What Ubuntu version were you running before you updated, and how did you install that? What method did you use to update to 14.04?

Also, could you try a newer kernel version? The latest ChromeOS uses 3.8.11, and armsoc works for us with that, both in a chroot and installed natively. Instructions on installing 14.04 with Linux 3.8.11 on an SD card can be found here: https://community.arm.com/docs/DOC-9494
