Updated from Ubuntu 13.10 to 14.04. Keyboard input is sluggish. When typing one letter appears after I type the next one.
While changing brightness using fn + brightness key notification appears but the brightness change after a long time or does not change at all. I am using a Lenovo ThinkPad L430. Note: I did not have any such problem with Ubuntu 13.10 or previous version in the same laptop. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/847001 Title: Adjusting display brightness is very slow on several Dell laptops To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-power-manager/+bug/847001/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
