After upgrading to ubuntu 16.04 LTS using Gallium 0.4 on AMD REDWOOD (DRM 2.43.0, LLVM 3.8.0). I get an unstable display when I plug in my external display through the VGA port. The system keeps cycling through the display options using only one display, then both then extended and then the other display. This happens every 10-15 seconds. --- ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/pcmC0D0p: herman 1805 F...m pulseaudio /dev/snd/controlC0: herman 1805 F.... pulseaudio /dev/snd/controlC1: herman 1805 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 16.04 HibernationDevice: RESUME=UUID=bf329afe-facd-48b6-8900-b8dac03d336b InstallationDate: Installed on 2014-04-25 (901 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) MachineType: Hewlett-Packard HP Pavilion dv6 Notebook PC Package: linux (not installed) ProcFB: 0 radeondrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.4.0-38-generic root=UUID=c9235e01-b5fa-4362-bfca-c6763140abba ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 4.4.0-38.57-generic 4.4.19 RelatedPackageVersions: linux-restricted-modules-4.4.0-38-generic N/A linux-backports-modules-4.4.0-38-generic N/A linux-firmware 1.157.3 Tags: xenial Uname: Linux 4.4.0-38-generic x86_64 UpgradeStatus: Upgraded to xenial on 2016-09-21 (22 days ago) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 11/07/2011 dmi.bios.vendor: Hewlett-Packard dmi.bios.version: F.29 dmi.board.asset.tag: Base Board Asset Tag dmi.board.name: 1448 dmi.board.vendor: Hewlett-Packard dmi.board.version: 65.38 dmi.chassis.type: 10 dmi.chassis.vendor: Hewlett-Packard dmi.chassis.version: N/A dmi.modalias: dmi:bvnHewlett-Packard:bvrF.29:bd11/07/2011:svnHewlett-Packard:pnHPPaviliondv6NotebookPC:pvr048E100000242B10000020000:rvnHewlett-Packard:rn1448:rvr65.38:cvnHewlett-Packard:ct10:cvrN/A: dmi.product.name: HP Pavilion dv6 Notebook PC dmi.product.version: 048E100000242B10000020000 dmi.sys.vendor: Hewlett-Packard To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1629917/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
