Yes! 4.7-rc2 booted (with noapic and nolapic) but the slowness-problem still remains there, tested with the disk utility again.
I tried to boot without noapic and nolapic but the computer seemed really slow and the graphical environment never came up. I was able to switch to console and reboot from there. Thank you Christopher for bringing the BIOS version to my attention. I thought I had upgraded the BIOS on the machine previously but apparently not. Will try to get it done but it such a hassle with these Windows- only BIOS upgrades X-| ** 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/1590154 Title: System slow unless using touchpad To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1590154/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
