Adding bskeggs in CC as Jerome Glisse told me he would be helpful. *** This bug has been marked as a duplicate of bug 1302847 *** |
Created attachment 1128204 [details] The strace which shows the issue with xrandr Description of problem: I'm running FC23 with Kernel 4.3.5-300.fc23.x86_64 on a Lenovo W541. It uses nouveau on a NVIDIA GPU Quadro K1100M (GK107GL) at PCI:1:0:0 (GPU-0) ( Memory: 2097152 kBytes, VideoBIOS: 80.07.ac.00.20 PCI Express Link width: 16X) When I launch some apps (not all), the whole system is freezing for 10s and then is back to normal. This doesn't prevent from using the system but that's pretty annoying. Dmesg reports : [81950.342001] nouveau 0000:01:00.0: DRM: resuming kernel object tree...

[81968.606688] nouveau 0000:01:00.0: DRM: suspending kernel object tree... I discussed that issue with Jerome Glisse which helped me at localizing where the issue is. He told me there is maybe an issue with the modesetting when someone is listing the connectors. I've been adding an strace of xrandr showing that 10sec freeze like in : 12:31:07.921386 poll([{fd=3, events=POLLIN}], 1, -1) = 1 ([{fd=3, revents=POLLIN}]) <9.057474> 12:31:16.978913 recvmsg(3, {msg_name(0)=NULL, msg_iov(1)=[{"\1\0\f\0\353\1\0\0d\245\f\0002\245\f\0\10\0\f\0/\0z\1\0\0\0\0\0\0\0\0", 4096}], msg_controllen=0, msg_flags=0}, 0) = 32 <0.000013> Version-Release number of selected component (if applicable): kernel-4.3.5-300.fc23.x86_64 xorg-x11-drv-nouveau-1.0.12-1.fc23.x86_64 How reproducible: 100% Steps to Reproduce: 1. Log into gnome 2. try xrandr in console or starts the configuration panel 3. locks occurs Actual results: System is locking for ~10sec Expected results: No lock ;) Additional info: I'm available for any testing.
