[Bug 1310489] Re: xorg.conf overwritten by booting system

 

Hi Alberto on my machine NVIDIA Optimus setup is no working even with
the latest version of  "ubuntu-drivers-common"  i.e.:(1:0.2.91.8),
although it does work with older version of this package i.e.
(1:0.2.91.4).  I have noticed one difference in the xorg.config file
generated by the new and old versions of gpu-manager. Basically when
using NVIDIA GPU as the main one i.e. "prime-select nvidia" the old gpu-
manager sets the "Driver" value for the "intel" device to "modesetting",
but the new gpu-manager sets the "Driver" value for the "intel" device
to "intel".

As far as I can understand by looking into the X server log setting  the
"Driver" value to "intel" instead of "modesetting" prevents the X server
from correctly identifying the screen on my laptop giving a black screen
on boot.

Please see the file attached to this post for a comparison of xorg.conf
files generated by the new and old gpu-managers.

Title:
  xorg.conf overwritten by booting system

Status in ubuntu-drivers-common package in Ubuntu:
  Fix Released
Status in ubuntu-drivers-common source package in Trusty:
  Fix Released

Bug description:
  Description:	Ubuntu 14.04 LTS
  Release:	14.04

  ----------------

  == SRU Request ==

  There is a regression in the gpu-manager that causes it to revert user
  changes right before the first reboot after enabling the fglrx driver
  or the nvidia driver on a system with hybrid graphics (Intel+AMD or
  Intel+NVIDIA). This causes the gpu-manager to remove the current
  xorg.conf and to switch to Mesa.

  [Impact]
   * This regression makes it almost impossible to use binary drivers on systems with hybrid graphics.

  [Test Case]
   * Make sure to be using a hybrid system with Intel+AMD or Intel+NVIDIA GPUs.

   * Make sure that the gpu-manager is not disabled (only necessary if
  you disabled it manually).

   * Remove all fglrx and nvidia drivers (keep the nvidia-common and the nvidia-prime packages):
     sudo apt-get --purge remove nvidia-331
     sudo apt-get --purge remove nvidia-331
     sudo apt-get --purge remove fglrx
     sudo apt-get --purge remove fglrx-updates

   * Install ubuntu-drivers-common from trusty-proposed.

   * Restart the system.

   * Install the binary driver (either fglrx or nvidia, according to the available discrete GPU), reboot, and check that the binary driver is enabled (attach your /var/log/gpu-manager.log)
      - Expected: the (AMD or NVIDIA) discrete GPU is enabled.
      - Bad behavior: the system switches back to the intel driver and the discrete GPU is not used, despite the fact that the system was configured properly.

  [Regression Potential]
   * Low. Systems that currently work will keep working as usual, the ones that currently fail should finally work.

  [Other Info]
   * N/A

  -----------------

  Hello,

  I am using a notebook with a quadcore AMD A10 and hybrid graficcard AMD/ATI Radeon HD 8650G / AMD/ATI Sun XT Radeon HD 8670A/8670M/8690M.
  After installing fglrx I generated the xorg.conf in the terminal with 'sudo aticonfig --adapter=all --initial' and it looked pretty good. Up to this point I was able to switch between the cards with the commands 'sudo aticonfig --px-dgpu' for the discrete card and 'sudo aticonfig --px-igpu' for the intigrated card to save power.
  After rebooting I realized that I was no longer able to switch between the cards and found that the xorg.conf will be overwritten whenever I modified it and reboot the system. The new (by boot) generated xorg.conf contains not the relevant information for switing between the cards.
  I attached both configuration in one file (xorg.conf.comparison). I will also provide the atisysteminfo-report.txt so far I will find the place where to attach.

  Edit: I fixed the error --> "AIGLX error: failed to open
  /usr/lib64/dri/fglrx_dri.so, error[/usr/lib64/dri/fglrx_dri.so: cannot
  open shared object file: No such file or directory]" but it changed
  not the bug of overwriting the xorg.conf.

  Regards,
  Uwe
