** Description changed: I've got a problem with some kernel modules (probably radeon) which cause screen problems. It occurs only on internal laptop screen. I found that problem is present in all kernels released after 2019-06-09 18:25. Last kernel which works corectly is v4.19.49 2019-06-09 10:04. v5.2-rc4 2019-06-09 18:25 has this bug and also v4.19.50 2019-06-11 13:06. So I think there are some changes in all kernel packages between hour 10:04 and 18:25 that day (2019-06-09) casue future problems. This may be problem with radeon modules cause screen goes strange when console shows "fb: switching to radeondrmfb from VESA VGA" (I remove "quiet splash" from GRUB menu). In this video I show described problem -> https://player.vimeo.com/video/382017028 I've tested those kernels: *Works correctly: v4.19/ 2018-10-22 23:50 v4.19.49/ 2019-06-09 10:04 v5.0.1/ 2019-03-10 08:30 v5.0.7/ 2019-04-05 22:40 v5.0.21/ 2019-06-04 08:28 v5.1.6/ 2019-05-31 15:32 v5.1.8/ 2019-06-09 09:29 *Not working correctly v4.14.163/ 2020-01-09 12:29 v4.19.50/ 2019-06-11 13:06 v4.19.94/ 2020-01-09 12:42 v5.0.0-37/ 2019-11-14 12:06 v5.1.9/ 2019-06-11 12:29 v5.1.10/ 2019-06-15 11:30 v5.1.11/ 2019-06-17 19:36 v5.2-rc4/ 2019-06-09 18:25 v5.2-rc5/ 2019-06-16 20:26 Quick Hardware info: * Compal FL90 * CPU: Intel Core 2 Duo T7500 * GPU: AMD Rv620 * System Description: Ubuntu 18.04.3 LTS x64 (xubuntu) * Kernel (works OK): 5.1.8-050108-generic #201906090832 SMP Sun Jun 9 08:35:40 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux + --- + ProblemType: Bug + ApportVersion: 2.20.9-0ubuntu7.9 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: master 1305 F.... pulseaudio + /dev/snd/controlC1: master 1305 F.... pulseaudio + CurrentDesktop: XFCE + DistroRelease: Ubuntu 18.04 + MachineType: - N/A + Package: linux (not installed) + ProcFB: 0 radeondrmfb + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-5.0.0-37-generic root=UUID=e286c111-0a34-4f09-9d80-ebb947347f62 ro + ProcVersionSignature: Ubuntu 5.0.0-37.40~18.04.1-generic 5.0.21 + RelatedPackageVersions: + linux-restricted-modules-5.0.0-37-generic N/A + linux-backports-modules-5.0.0-37-generic N/A + linux-firmware 1.173.14 + Tags: bionic + Uname: Linux 5.0.0-37-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo + _MarkForUpload: True + dmi.bios.date: 06/18/2008 + dmi.bios.vendor: COMPAL + dmi.bios.version: 1.18 + dmi.board.name: IFL90 + dmi.board.vendor: - + dmi.board.version: IFT00 + dmi.chassis.asset.tag: - + dmi.chassis.type: 10 + dmi.chassis.vendor: No Enclosure + dmi.chassis.version: N/A + dmi.modalias: dmi:bvnCOMPAL:bvr1.18:bd06/18/2008:svn-:pnN/A:pvrN/A:rvn-:rnIFL90:rvrIFT00:cvnNoEnclosure:ct10:cvrN/A: + dmi.product.family: Compal + dmi.product.name: N/A + dmi.product.sku: Compal + dmi.product.version: N/A + dmi.sys.vendor: - ** Attachment added: "AlsaInfo.txt" https://bugs.launchpad.net/bugs/1859352/+attachment/5319843/+files/AlsaInfo.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1859352 Title: Graphic driver (radeon) screen problem in kernels released after 2019-06-09 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1859352/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
