Is this likely to be resolve in the near future? What drawbacks are there to using the mainline kernel? I'm about to purchase a portable monitor for my Kubuntu 13.10 laptop, and have to plan accordingly. I'd like to use a DisplayLink monitor like http://www.amazon.com/ASUS- Portable-USB-Powered-Monitor-MB168B/dp/B00FE690DI/ or http://www.amazon.com/AOC-e1659Fwu-16-Inch-USB-Powered- Portable/dp/B00CMKOVMO/
What will I lose if I upgrade to the mainline kernel (2011 Dell XPS L501X)? What's the likelihood that Ubuntu kernels will fix this problem within the next month? This bug is 4 months in process, and no updates in the last month and still in the Triaged state.

However, when upgrading to 3.11.0-11-generic, X11 fails to open the DRI device with: [ 8.868] (EE) open /dev/dri/card1: Resource temporarily unavailable Reverting to 3.11.0-031100-generic fixes the problem. Upgrading to current mainline (3.12.0-999.201310030405) also fixes the problem (but causes lots of kernel BUG messages). In both cases, the kernel correctly creates the /dev/fb1 and /dev/dri/card1 devices. There are no error messages in the kernel log. --- ApportVersion: 2.12.7-0ubuntu1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: ubuntu 2883 F.... pulseaudio CasperVersion: 1.336ubuntu1 CurrentDesktop: Unity DistroRelease: Ubuntu 14.04 LiveMediaBuild: Ubuntu 14.04 LTS "Trusty Tahr" - Alpha amd64 (20131203) MachineType: LENOVO 3444F8U MarkForUpload: True Package: linux (not installed) ProcFB: 0 inteldrmfb 1 udldrmfb ProcKernelCmdLine: file=/cdrom/preseed/username.seed boot=casper initrd=/casper/initrd.lz quiet splash -- maybe-ubiquity ProcVersionSignature: Ubuntu 3.12.0-5.13-generic 3.12.2 RelatedPackageVersions: linux-restricted-modules-3.12.0-5-generic N/A linux-backports-modules-3.12.0-5-generic N/A linux-firmware 1.117 Tags: trusty Uname: Linux 3.12.0-5-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo WifiSyslog: dmi.bios.date: 02/04/2013 dmi.bios.vendor: LENOVO dmi.bios.version: G6ET93WW (2.53 ) dmi.board.asset.tag: Not Available dmi.board.name: 3444F8U dmi.board.vendor: LENOVO dmi.board.version: Win8 Pro DPK TPG dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvrG6ET93WW(2.53):bd02/04/2013:svnLENOVO:pn3444F8U:pvrThinkPadX1Carbon:rvnLENOVO:rn3444F8U:rvrWin8ProDPKTPG:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 3444F8U dmi.product.version: ThinkPad X1 Carbon dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1234818/+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
