Aug 19 13:42:34 tohuvabohu.balabit kernel: [drm:drm_wait_vblank [drm]] *ERROR* Unsupported type value 0x139, supported mask 0x7400003f
My environment is Cinnamon and here is my versions xorg-x11-server-Xorg.x86_64 1.17.2-2.fc22 @System cinnamon.x86_64 2.6.13-2.fc22 @System xorg-x11-drv-nouveau.x86_64 1:1.0.11-2.fc22 @System 4.1.4-200.fc22.x86_64 I'm seeing similar: [drm:drm_wait_vblank [drm]] *ERROR* Unsupported type value 0x4b, supported mask 0x7400003f [drm:drm_wait_vblank [drm]] *ERROR* Unsupported type value 0x4b, supported mask 0x7400003f [drm:drm_wait_vblank [drm]] *ERROR* Unsupported type value 0x400004b, supported mask 0x7400003f My setup also has dual monitors with Intel/Nvidia. I've only started seeing this recently (possibly since I started using HDMI rather than VGA for one of the screens). Also with KDE on F22. Meanwhile I completely removed bumblebee. As a result, doing an explicit # modprobe nouveau via a console is no longer necessary before login -- good. However, the flood of "Unsupported type value" errors is still present. My setup is currently working with kernel 4.1.3-201.fc22.x86_64. For nouveau users out there: Note that the latest kernel (4.1.6-200.fc22.x86_64) no longer works for me (KDE 5 Plasma setup on Lenovo W530 with "Optimus"), see https://bugzilla.redhat.com/show_bug.cgi?id=1260053 Output of xrandr for my dual-monitor setup: $ xrandr -q Screen 0: minimum 8 x 8, current 4480 x 1440, maximum 32767 x 32767 LVDS1 connected 1920x1080+0+360 (normal left inverted right x axis y axis) 344mm x 193mm 1920x1080 60.02*+ 50.03 1400x1050 59.98 1600x900 60.00 1280x1024 60.02 1280x960 60.00 1368x768 60.00 1280x720 60.00 1024x768 60.00 1024x576 60.00 960x540 60.00 800x600 60.32 56.25 864x486 60.00 640x480 59.94 720x405 60.00 640x360 60.00 VGA1 disconnected (normal left inverted right x axis y axis) VIRTUAL1 disconnected (normal left inverted right x axis y axis) LVDS-1-2 disconnected (normal left inverted right x axis y axis) VGA-1-2 disconnected (normal left inverted right x axis y axis) DP-1-1 disconnected (normal left inverted right x axis y axis) DP-1-2 disconnected (normal left inverted right x axis y axis) DP-1-3 connected 2560x1440+1920+0 (normal left inverted right x axis y axis) 597mm x 336mm 2560x1440 59.95*+ 1920x1200 59.88 1920x1080 60.00 50.00 59.94 24.00 23.98 1920x1080i 60.00 50.00 59.94 1600x1200 60.00 1680x1050 59.95 1280x1024 75.02 60.02 1280x800 59.81 1152x864 75.00 1280x720 60.00 50.00 59.94 1024x768 75.08 60.00 800x600 75.00 60.32 720x576 50.00 720x576i 50.00 720x480 60.00 59.94 720x480i 60.00 59.94 640x480 75.00 60.00 59.94 720x400 70.08 1280x1024 (0x76) 108.000MHz h: width 1280 start 1328 end 1440 total 1688 skew 0 clock 63.98KHz v: height 1024 start 1025 end 1028 total 1066 clock 60.02Hz 1024x768 (0x7d) 65.000MHz h: width 1024 start 1048 end 1184 total 1344 skew 0 clock 48.36KHz v: height 768 start 771 end 777 total 806 clock 60.00Hz 800x600 (0x7f) 40.000MHz h: width 800 start 840 end 968 total 1056 skew 0 clock 37.88KHz v: height 600 start 601 end 605 total 628 clock 60.32Hz 640x480 (0x88) 25.175MHz h: width 640 start 656 end 752 total 800 skew 0 clock 31.47KHz v: height 480 start 490 end 492 total 525 clock 59.94Hz This has now gone away for me with a bunch of updates that included new kernel, new KDE packages and new mesa stuff. Looks like this is fixed. Please let us know if it happens again (or still happens for you) so we can reopen it. After a reboot it's back. I can't spot how to repoen this bug. Paul, I also noted that the drm_wait_vblank errors do not occur on every boot -- for me, the journal spamming occurs with roughly 3 out of 4 reboots. This is still for kernel 4.1.3-201.fc22.x86_64, because the external monitor remains black for me with newer kernels (4.1.6-200.fc22 and 4.1.6-201.fc22), where I am getting nouveau errors kernel: nouveau E[ PDISP][0000:01:00.0][0x00000006] 06:0006:0f48: link training failed in the journal. Are these newer kernels working for you? (One difference we have is that you are using HDMI, whereas I am using DP for the external monitor.) B.t.w., what's your setting for KDE Display Configuration > Primary display ? This recent boot was the first time I noticed it behaving correctly. I've not had any trouble with any particular kernel version (currently using 4.1.6-201). My primary display is ""Goldstar Company Ltd 24MP55 (HDMI-1-1)" (so not the integral "Laptop Screen"). See also: https://bugs.freedesktop.org/show_bug.cgi?id=92327 Bug 92327 - Tearing and drm_wait_vblank kernel log spam with reverse PRIME (intel+nouveau) The problem is still present with Plasma 5.5.0, KDE frameworks 5.17 and kernel 4.2.8-200 (fully updated F22 system) -- it shows in roughly 3 out of 4 boot/login cycles. Temporary workaround of original bug description still applies.

Created attachment 1052348 [details] Journal showing nouveau being loaded and drm errors, and Xorg.0.log Description of problem: My dual monitor setup with KDE Plasma 5 works on an "Optimus" laptop, but the journal is flooded (at high rate) with kernel drm errors such as [drm:drm_wait_vblank [drm]] *ERROR* Unsupported type value 0x133, supported mask 0x7400003f [drm:drm_wait_vblank [drm]] *ERROR* Unsupported type value 0x4000133, supported mask 0x7400003f I'm on a Lenovo W530 laptop with integrated Intel and discrete Nvidia graphics ("Optimus" technology) and have a working KDE 5 dual monitor setup (LVDS + DP). The setup requires that I modprobe the nouveau driver manually before login to KDE. It gives me a composite screen that extends over both the LVDS and the external monitor and has very smooth performance when moving windows -- a positive surprise given that the nouveau driver is involved. This is in fact the *only* way I got an external monitor to work on Fedora 22 with KDE Plasma 5. The rate of the above error messages is **hundreds per minute** and hence rapidly fills the journal, besides slowing down the system. As a temporary workaround, the error messages can be reliably stopped by setting KDE Display Configuration > Primary display to "No Primary Output". Fortunately, this does not immediately move the KDE Panel to the smaller laptop screen, but it does so when I logout/login, so this setting is not suitable as a permanent solution. As I often need the KDE Panel on the bigger external monitor, I prefer to set KDE Display Configuration > Primary display to my external monitor for this dual monitor kscreen setup. The fact that the drm error messages stop when I set the Primary display to "No Primary Output" indicates that kwin is in control of the vblank functionality but does not always do so correctly. Version-Release number of selected component (if applicable): kwin-libs-5.3.2-1.fc22.x86_64 kwin-5.3.2-1.fc22.x86_64 kf5-kwindowsystem-5.11.0-1.fc22.x86_64 xorg-x11-drv-intel-2.99.917-12.20150615.fc22.x86_64 xorg-x11-drv-nouveau-1.0.11-2.fc22.x86_64 mesa-dri-drivers-10.5.4-1.20150505.fc22.x86_64 (mesa-dri-drivers-10.6.1-1.20150629.fc22.x86_64 not installed because it causes modprobe-ing nouveau.ko to fail) libdrm-2.4.61-3.fc22.x86_64 libdrm-devel-2.4.61-3.fc22.x86_64 libdrm-2.4.61-3.fc22.i686 # uname -r 4.0.7-300.fc22.x86_64 How reproducible: 100% Steps to Reproduce: 1. Boot 2. Before login, 'sudo modprobe nouveau' via a console 3. Login to KDE Plasma 5 4. Setup KDE Display Configuration for a composite screen extending over both Laptop Screen (LVDS) and Ext. Monitor (DP...). Set Primary display = <Ext. Monitor> Actual results: Working screen, with KDE panel on external monitor, but dmesg is flooded with kernel drm errors such as [drm:drm_wait_vblank [drm]] *ERROR* Unsupported type value 0x133, supported mask 0x7400003f [drm:drm_wait_vblank [drm]] *ERROR* Unsupported type value 0x4000133, supported mask 0x7400003f or [drm:drm_wait_vblank [drm]] *ERROR* Unsupported type value 0x73, supported mask 0x7400003f [drm:drm_wait_vblank [drm]] *ERROR* Unsupported type value 0x4000073, supported mask 0x7400003f Expected results: No flooding with drm error messages, even if KDE is unable to use VSync with the given dual monitor setup. Additional info: Based on KDE System Settings > Display and Monitor > Compositor: - Scale method : Crisp - Rendering backend: XRender (1) - Tearing prevention ("vsync"): Automatic (2) (1) Changing this setting to OpenGL 2.0 or OpenGL 3.1 does not eliminate the drm_wait_vblank errors but causes mouse pointer movements to leave "traces" on the screen. (2) Changing this setting does not eliminate the drm_wait_vblank errors
