Public bug reported: Atm this isn't a reproducible bug using only repo packages as the most clearly affected app, mpv, doesn't have Osc enabled, though it could be in future Debian releases. (Osc = on screen controller
So perfectly understandable for this report to not be acted upon for that reason & the somewhat extensive test case. Best Test case: Have 2 current installs of either 13.10 or 14.04 with grub-pc on an Intel graphics machine, preferably intel 4000 Install libvdpau-va-gl on both installs Install an Osc enabled mpv, if desired have both saucy & trusty Osc enabled builds here - (Osc uses liblua5.2 https://launchpad.net/~mc3man/+archive/mpv-tests Boot to the install that grub-pc is not configured on to confirm Osc works without issue when using libvdpau-va-gl like such - >From terminal - env VDPAU_DRIVER=va_gl mpv --hwdec=vdpau --vo=vdpau /path/to/a/AVC encoded vid Once vid starts move mouse into window to expose Osc, video should continue with out issue while Osc is exposed. Then boot to grub configured install & repeat above. Once Osc is exposed video rendering will become very late, slow motion or worse. Move cursor out of window to hide Osc & the video will catch up in a sec. or 2. Expose Osc & again video will falter.. Connection to grub-pc - On the grub configured install 'gfxmode' is set in 2 places corresponding to the 00_header & 10_linux templates. If those 2 entries for the grub configured install are removed from grub.cfg then on reboot Osc in mpv works fine. Here I altered the 2 templates, then ran an update-grub to affect the same thing as manually editing grub.cfg - 00_header --- /etc/grub.d/00_header 2013-11-22 21:44:24.334026219 -0500 +++ /etc/grub.d/00_header 2013-11-22 21:44:24.334026219 -0500 @@ -202,7 +202,6 @@ fi cat << EOF - set gfxmode=${GRUB_GFXMODE} load_video insmod gfxterm EOF 10_linux --- /etc/grub.d/10_linux 2013-11-22 21:55:29.006117251 -0500 +++ /etc/grub.d/10_linux 2013-11-22 21:55:29.006117251 -0500 @@ -150,10 +150,6 @@ echo " load_video" | sed "s/^/$submenu_indentation/" fi fi - if ([ "$ubuntu_recovery" = 0 ] || [ x$type != xrecovery ]) && \ - ([ "x$GRUB_GFXPAYLOAD_LINUX" != x ] || [ "$gfxpayload_dynamic" = 1 ]); then - echo " gfxmode \$linux_gfx_mode" | sed "s/^/$submenu_indentation/" - fi echo " insmod gzio" | sed "s/^/$submenu_indentation/" ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: libvdpau-va-gl1 0.2.0-1 ProcVersionSignature: Ubuntu 3.12.0-5.13-generic 3.12.2 Uname: Linux 3.12.0-5-generic x86_64 ApportVersion: 2.12.7-0ubuntu2 Architecture: amd64 CurrentDesktop: Unity Date: Tue Dec 10 18:47:17 2013 SourcePackage: libvdpau-va-gl UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: libvdpau-va-gl (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug trusty -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1259754 Title: Video rendering can break with certain osd on installs where grub-pc is configured (using the default grub options To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvdpau-va-gl/+bug/1259754/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
