Public bug reported: CID: 201107-8258 Lenovo ThinkPad Edge E525
With the open-source radeon driver, there is no display after resume from suspend. But the system still working, I could open a terminal and reboot the laptop with sudo reboot. There is no such problem with proprietary drivers, but the brightness control issue (bug 1243508) will make both of these two bugs become a blocker Radeon driver version: ubuntu@201107-8258:~$ dpkg -l | grep radeon ii libdrm-radeon1 2.4.43-0ubuntu0.0.2 Userspace interface to radeon-specific kernel DRM services -- runtime ii radeontool 1.6.2-1.1 utility to control ATI Radeon backlight functions on laptops ii xserver-xorg-video-radeon-lts-raring 1:7.1.0-0ubuntu2~precise1 X.Org X server -- AMD/ATI Radeon display driver ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: xserver-xorg-video-radeon-lts-raring 1:7.1.0-0ubuntu2~precise1 ProcVersionSignature: Ubuntu 3.8.0-29.42~precise1-generic 3.8.13.5 Uname: Linux 3.8.0-29-generic x86_64 ApportVersion: 2.0.1-0ubuntu17.5 Architecture: amd64 Date: Wed Oct 23 05:27:06 2013 InstallationMedia: Ubuntu 12.04.3 LTS "Precise Pangolin" - Release amd64 (20130820.1) MarkForUpload: True ProcEnviron: TERM=xterm PATH=(custom, no user) LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: xserver-xorg-video-ati-lts-raring UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: xserver-xorg-video-ati-lts-raring (Ubuntu) Importance: Undecided Assignee: Anthony Wong (anthonywong) Status: New ** Tags: 201107-8258 amd64 apport-bug blocks-hwcert blocks-hwcert-enablement precise running-unity taipei-lab -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati-lts-raring in Ubuntu. https://bugs.launchpad.net/bugs/1243621 Title: AMD Radeon 6480G[1002:9648] No display after resume from suspend with radeon driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati-lts-raring/+bug/1243621/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
