Christopher M. Penalver, I have not had availability to test version 18.04 on a new disc but I have more information:
- After updating the packages xorg-server....hwe... I decided to test the Open Source drivers again and got improvements. - Due to these improvements and to the system crashing less, I detected a pattern in the crashes. It may not be related but crashes usually happen when I adjust the size of a window manually. I'll let you know as soon as I have more information. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1746638 Title: [GeForce 6150SE nForce 430] PC freezes and crashes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1746638/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
