[Bug 1358936] Re: [gm45] L-shaped memory with invalid swizzling

  Thread Previous • Date Previous • • Thread Next 
Alexander Lindo, as per
https://www.asus.com/Notebooks/K50IJ/HelpDesk_Download/ an update to
your computer's buggy and outdated BIOS is available (218). If you
update to this following https://help.ubuntu.com/community/BIOSUpdate
does it change anything?

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. As well, 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 New.
Otherwise, please mark this as Invalid.

Thank you for your understanding.

** Description changed:

  I have been having an issue with garbled graphics on an ASUS K50IJ
  Laptop with Intel GMA X4500 integrated graphics.
  
  It is a difficult bug to recreate in a timely fashion as it requires you
  to be on the system for a decent amount of time (like an hour, sometimes
  less). Usage scenario to recreate this bug: would be to gradually build
  up to 10 Firefox or Google Chrome tabs. Minimize the applications, Open
  a 4000x3000 pixel photo in GIMP, do some editing. After using the
  computer for a while, go to the launcher and click Firefox or Chrome.
  Close Firefox or Chrome and then close GIMP. Firefox will take a while
  to close and while the hard drive is loading, the screen will suddenly
  become garbled.
  
  I've been a user of Ubuntu since version 6.06 (Dapper Drake) and have
  been using it exclusively on this laptop since version 12.04. I have not
  had this issue until 14.04.
  
- The temporary workaround is to log out and log back in, after which the
- graphics are back to normal. I also checked to see if it was a memory
- issue but System Monitor does not appear to display such an issue.
