Dominik, as per http://www.samsung.com/pl/support/model/NP-R540-JA07PL an update to your computer's buggy and outdated BIOS is available (08JV). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it address the issue?
If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. Also, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible, and the information above is provided, then please mark this report Status Confirmed. Otherwise, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-08jv -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1512454 Title: Refresh change colours Status in xorg package in Ubuntu: Incomplete Bug description: I had experienced few times that refreshing window causes some places to lose right information about colour. I mean that colours change to different for e.g. grey become yellowish, and strips are visible. Also in web browser some letters disappear. It is happening not often, maybe about 2/3 times per month. I am using Ubuntu 14.04, with following Hardware: Intel core I5 540M 2.53 GHz x 2 with Intel Ironlake Mobile graphics. System Is 64 bit version. 3,7GiB Ram. I'm using two screens with different size. First one is built-in laptop screen with resolution 1366x768 (16:9) and second one is Hitachi 22HXJ06U with resolution 1920x1080 (16:9). This happened to me also in Ubuntu 15.04, and before on Ubuntu 14.10. (In all cases the same hardware and two screens). Until now I notice this bug only when on firefox so I thought it could be something wrong with firefox, but today I noticed this bug on Terminal Window. I cannot really provide information how to create this bug - twice it happened on facebook when board automatically refreshed, and today it happened on Terminal when I clicked on firefox. I tried to repeat the problem with terminal, using the same commands but without positive results. Bug is fixing when window / application getting refreshed - scrolling up / down or moving window on screen fixing it. Creating Screenshot doesn't fixing it (done by default Print Screen with animation that everything becoming white and going to normal imag e) I also checked logs (/var/log/Xorg.0.log) but I dont see any error message or something - log finishing after screen setting up. I attached picture with example in firefox window (screenshots was bit edited - facebook's board, chat and chat list been deleted). --- .tmp.unity.support.test.0: ApportVersion: 2.14.1-0ubuntu3.18 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true DistUpgraded: Fresh install DistroCodename: trusty DistroRelease: Ubuntu 14.04 DistroVariant: ubuntu DkmsStatus: virtualbox, 4.3.10: added ExtraDebuggingInterest: Yes, including running git bisection searches GraphicsCard: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 18) (prog-if 00 [VGA controller]) Subsystem: Samsung Electronics Co Ltd Device [144d:c06a] InstallationDate: Installed on 2015-10-17 (23 days ago) InstallationMedia: Ubuntu 14.04.3 LTS "Trusty Tahr" - Beta amd64 (20150805) Lsusb: Bus 002 Device 002: ID 8087:0020 Intel Corp.
