Red Hat Bugzilla – Bug 843985
Horysontal lines after kernel boots on sandybridge graphics
Last modified: 2015-12-21 04:14:32 EST
Description of problem:
On HP pro 3420 AiO PC there is a horysontal lines appears starting from the moment of booting the kernel immidiatelly after grub finishes. GRUB screen is noremal and after kernel boots it starting to have lines moving across the display
Version-Release number of selected component (if applicable):
Not sure if it is video driver but version of intel driver is 2.19.0-5.fc17.x86_64
Steps to Reproduce:
1. Power on PC
2. Install Fedora 17
3. Enjoy lines
Horisontal lines running across the monitor
All the drivers (intel, vesa, fbdev) are having the same behaviour - lines.
Tried several methods to make things work.
1) per http://www.linuxquestions.org/questions/linux-hardware-18/intel-sandy-bridge-graphics-running-lines-on-screen-942450/
"Added to /etc/default/grub:
and /etc/modprobe.d/i915-kms.conf is changed:
options i915 modeset=0"
Result is 800x600 resolution with no lines woth no possibility to set up normal resolution
2) palyed with xorg.conf with setting up modelines manually.
Result is failed graphic mode
3) removing one or all drivers (intel, vesa, fbdev). If any of them is installed lines are present. If all are removed PC is freezed.
4) different combinations of 1,2,3 which seemed me reasonable.
For now PC is working normally on 800x600 only.

Thank you in advance
One more thing. Here http://askubuntu.com/questions/94985/ubuntu-driver-for-intel-sandybridge-ivybridge-graphics and here http://www.cyberforum.ru/ubuntu-linux/thread398662-page4.html (discussion on Russian but final post prety clear) people calims they solved the problem. At least screen resolution is ok. But similar thing didn't seem to work for me.(In reply to comment #0)
Infortunatelly I had a typo and seems http://askubuntu.com/questions/94985/ubuntu-driver-for-intel-sandybridge-ivybridge-graphics and here http://www.cyberforum.ru/ubuntu-linux/thread398662-page4.html are solving horysontal lines problem
into /etc/default/grub and doing grub2-mkconfig -o /boot/grub2/grub.cfg does the job.
Regarding perfomance have nothing to say so far as no clear testing done.
To make clear what lines I'm talking about please refer to this http://www.youtube.com/watch?v=5lKYLggdAS8 video.
overall BKM is found but seems more reliable solution without nomodeset option is needed.
Thank you very much for your report.
Fedora Bugzappers volunteer triage team
This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '17'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 17's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 17 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged change the
'version' to a later Fedora version prior to Fedora 17's end of life.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
