[Desktop-packages] [Bug 1692437] Re: Monitors on second GPU not working after upgrade to zesty
After going on the #radeon channel on Freenode, we narrowed the problem down to the switcheroo-control package. We started by hand making an xorg.conf file and disabling gpu-manager, but still had issues. Looking at the dmesg log, we saw that the discrete gpu is enabled at first, then disabled sometime in the systemd start up. After trying to disable various things, including switcheroo, from the kernel parameters and having the problem still occur, we narrowed it down to being a service that was writing to `/sys/kernel/debug/vgaswitcheroo/switch`. I looked at my enabled services, and saw `switcheroo-control`, after disabling, everything started working again. Given that the package was integrated into gnome in late 2016 [0][1], it lines up timewise with when I started having problems.

[Desktop-packages] [Bug 1692437] Re: Monitors on second GPU not working after upgrade to zesty
I filmed my computer boot up to better show what happens. The right monitor is on the integrated video card (the R7), and doesn't show anything initially. The center and left monitor turn on and mirror each other during boot, and show grub and most of the kernel and systemd messages, then at some point all output is sent to the right monitor. I believe the systemd log says something along the lines of "detecting all video cards" at that point. ** Attachment added: "Computerbootup.webm" https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1692437/+attachment/5235238/+files/Computerbootup.webm -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1692437 Title: Monitors on second GPU not working after upgrade to zesty Status in Light Display Manager: New Status in xserver-xorg-driver-radeonhd: Invalid Status in lightdm package in Ubuntu: New Bug description: I'm not 100% sure this is the right package to file the bug against, but since upgrading to zesty the two monitors on my second GPU are no longer detected once I reach the greeter screen at login time.
