SUMMARY:- Installed upscreen kernel, still got problems. See below for details:-
Did this on personal computer... ================================ Downloaded these files:- total 58M -rw-rw-r-- 1 ian ian 11M Oct 19 12:18 linux-headers-4.14.0-041400rc5_4.14.0-041400rc5.201710152230_all.deb -rw-rw-r-- 1 ian ian 657K Oct 19 12:18 linux-headers-4.14.0-041400rc5-generic_4.14.0-041400rc5.201710152230_i386.deb -rw-rw-r-- 1 ian ian 48M Oct 19 12:19 linux-image-4.14.0-041400rc5-generic_4.14.0-041400rc5.201710152230_i386.deb Put onto flash drive. Did this on the Samsung NC10 NetBook (hostname "hawking") with the graphics problem. ==================================================================================== Copied into ~/usk folder on NetBook Did a sudo dpkg -i *.deb Rebooted. Using this kernel:- =================== Linux hawking 4.14.0-041400rc5-generic #201710152230 SMP Mon Oct 16 02:43:31 UTC 2017 i686 i686 i686 GNU/Linux When NetBook connected to an external monitor ============================================= It appears that, when the system is connected to an external monitor, the graphics corruption doesn't happen. However, the login screen is black with a mouse pointer. Typed password in blind - no luck. Did it a few times, eventually managed to login. On the external monitor, the display is perfect. On the NetBook screen, it is almost perfect - the task bar at the bottom of the screen is not present. Note: with this kernel, the system can't see my Ethernet connection. When NetBook only using built in screen ======================================= Boot screen left hand side 80% black with some smudges of text, remainder 20% of screen is black with the occasional part of a kernel message, later in boot process is blue. Login screen left hand side 80% black, remainder perfect Typed password in blind. Login screen left hand side 80% black, remainder perfect - even part of the taskbar is visible. Anomaly - when I do a screen shot by pressing the Print Screen key, when viewed on my personal computer, the image is *perfect*. I'm no graphics developer but it suggests to me the frame buffer is OK, so the problem is something else. -- -- ACCU - Professionalism in programming - http://www.accu.org -- My writing - https://sites.google.com/site/ianbruntlett/ -- Free Software page - https://sites.google.com/site/ianbruntlett/home/free-software ** Tags added: kernel-bug-exists-upstream ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1724639 Title: Graphics problem - 80% of the Left hand side of screen solid black To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1724639/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
