yes, this kernel boots fine: Linux 3.18.0-031800rc1-generic #201410192135 SMP Mon Oct 20 01:37:04 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
The backlight issue works much better now. One thing I noticed is that when I redock the laptop, the backlight goes off. Increasing the backlight via the Fn+F9 key does not work immediately. It takes a few seconds before it accepts new controls. This might, however, be caused by some scripts which react to the laptop being docked <https://github.com/martin-ueding/thinkpad-scripts/>. I thought I removed them, but maybe there are still traces. Anyway, I received this, which may be relevant: [ 147.418106] ACPI: \_SB_.GDCK: docking [ 147.600681] [drm:drm_edid_block_valid] *ERROR* EDID checksum is invalid, remainder is 221 [ 147.600685] Raw EDID: [ 147.600687] 00 ff ff ff ff ff ff 00 f0 9e 30 00 00 00 00 33 [ 147.600688] 17 01 04 a5 34 20 78 26 4c a5 a7 55 4d a2 26 10 [ 147.600689] 50 54 a1 08 00 b3 00 95 00 81 00 a9 40 81 80 d1 [ 147.600690] c0 81 c0 01 01 28 3c 80 a0 70 b0 23 40 30 20 36 [ 147.600691] 00 06 44 21 00 00 1a 00 00 00 fd 00 32 4c 18 5e [ 147.600691] 11 00 0a 20 20 20 20 20 20 00 00 00 fc 00 48 50 [ 147.600692] 20 5a 32 34 69 0a 20 20 20 20 20 00 00 00 ff 00 [ 147.600693] 43 4e 34 33 35 31 30 42 42 32 0a 20 20 00 68 ff [ 147.646162] usb 4-1.3: new high-speed USB device number 4 using ehci-pci [ 147.738603] usb 4-1.3: New USB device found, idVendor=0424, idProduct=2514 [ 147.738607] usb 4-1.3: New USB device strings: Mfr=0, Product=0, SerialNumber=0 Given that it works better, I'm adding the kernel-fixed-upstream-3.18-rc1 tag ** Tags added: kernel-fixed-upstream-3.18-rc1 ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1386597 Title: Oopses when ejecting thinkpad x230t from docking station with extern DP monitor Status in “linux” package in Ubuntu: Confirmed Bug description: I get Oopses in dmesg when undocking the laptop from the docking station, which did not happen in previous kernels: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1386597/+attachment/4247119/+files/log.txt ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: linux-image-3.13.0-37-generic 3.13.0-37.64 ProcVersionSignature: Ubuntu 3.13.0-37.64-generic 3.13.11.7 Uname: Linux 3.13.0-37-generic x86_64 ApportVersion: 2.14.1-0ubuntu3.5 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: muelli 2559 F.... pulseaudio Date: Tue Oct 28 10:27:30 2014 HibernationDevice: RESUME=UUID=82ba58b5-df3f-46fa-858a-368103173605 InstallationDate: Installed on 2014-01-22 (278 days ago) InstallationMedia: Ubuntu-GNOME 13.10 "Saucy Salamander" - Release amd64 (20131017) MachineType: LENOVO 3437B52 ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-3.13.0-37-generic.efi.signed root=/dev/mapper/ubuntu--gnome--vg-root ro quiet splash vt.handoff=7 PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: Home directory not accessible: Permission denied No PulseAudio daemon running, or not running as session daemon.
