This problem is not fixed, or at least not fully. I am running Xubuntu 14.04 on the 3.13.0-47-generic kernel. I have Nvidia optimus graphics on my laptop with dual Intel GMA HD and Nvidia GeForce GTX 860M graphics cards. I have the ubuntu-drivers-common version 1:0.2.91.8, nvidia drivers version 331.113, and nvidia-prime version 0.6.2.
I've noticed the following: 1. When I have the Nvidia prime profile selected and reboot, the system leaves my xorg.conf alone. The gpu-manager.log says that I previously had 2 cards, I have 2 cards now, and nothing changed. 2. When I switch to the Intel prime profile from the Nvidia prime profile and reboot, the gpu-manager.log says I previously had 2 cards and I have 2 cards now and the system did not change, but IT DELETES xorg.conf anyway! 3. Whenever I reboot with the Intel prime profile in effect, the gpu- manager.log always says I previously had 1 card, I have 2 cards now, and the system has changed. Then it renames xorg.conf to xorg.conf.currentdate. 4. When I switch from the Intel prime profile to the Nvidia prime profile, the gpu-manager.log says I previously had 1 card, I now have 2 cards, and the system has changed. It then tries to remove xorg.conf, which isn't there anyway, and then regenerates xorg.conf. One weird thing is it usually says Found "/dev/dri/card0", driven by "i915", but in this case only it says Found "/dev/dri/card1", driven by "i915". Why would the card number change? Without knowing anything about the internals here, it sure looks like there is a bug in how gpu-manager counts cards, or if it gets that info from something else, then that something has a bug. ** Attachment added: "GPU Manager logs" https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1310489/+attachment/4339543/+files/gpu%20manager%20logs -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310489 Title: xorg.conf overwritten by booting system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1310489/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
