[Bug 1581270] Re: Hybrid Graphics: [drm:si_resume [radeon]] *ERROR* si startup failed on resume
"Tenten36 (tenten) wrote on 2016-07-27: The problem still exists with kernel 4.6 and 4.7 from the mainline build. $ DRI_PRIME=1 glxgears gives black screen" That seems like a regression or the newest kernels weren't patched. Currently using 4.4.14 and it still works. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1581270 Title: Hybrid Graphics: [drm:si_resume [radeon]] *ERROR* si startup failed on resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1581270/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1581270] Re: Hybrid Graphics: [drm:si_resume [radeon]] *ERROR* si startup failed on resume
Some news. I updated the kernel to 4.4.13. Now I don't have error messages is dmesg. Added radeon.dpm=1 radeon.modeset=1 to /etc/default/grub file (not sure if everything is needed). sudo update-grub and reboot Although I still cannot switch between the cards with DDIS, but I can run specific programs with the dedicated AMD, using DRI_PRIME=1 programpathname. That is already quite good, because I don't need the dedicated for browsing the web or so. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1581270 Title: Hybrid Graphics: [drm:si_resume [radeon]] *ERROR* si startup failed on resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1581270/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Don't know if it helps, but I ran DRI_PRIME=1 glxinfo|grep "OpenGL renderer". Seems like the only way to get some reaction from the dedicated one other than black screen.

[Bug 1581270] Re: Hybrid Graphics: [drm:si_resume [radeon]] *ERROR* si startup failed on resume
Would like to join in on this bug. I have a laptop with Intel Haswell and AMD Radeon HD 8850M / R9 M265X. I can't change to the dedicated GPU no matter how I try. My error messages in dmesg are basically the same as mentioned above. Also, when I stop lightdm I get the title error: [drm:si_resume [radeon]] *ERROR* si startup failed on resume. Using DIS on vgaswitcheroo file just gives me a black screen. I am on Ubuntu 16.04. Tried with the Grub parameters mentioned and without them. Still have the issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1581270 Title: Hybrid Graphics: [drm:si_resume [radeon]] *ERROR* si startup failed on resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1581270/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
