Ubuntu 13.10 is causing me major headaches with my AMD/ATI HD 5770 GPU. Below is a list of problems I am currently encountering.
1) The boot time is extended by at least 25s after installing catalyst 13.11 beta. Using open source radeon drivers, my boot time till the login screen is ~10s. With catalyst 13.11 beta installed, the boot time increases to ~35s. This was not the case in Ubuntu 13.04, 12.10 or 12.04. I have done the driver installation manually (instructions from wiki.cchtml.com) and using software center and there is no difference. I have not tried the catalyst 13.8 beta driver.
2) The delay between logging in and unity being displayed is ~10-15s for BOTH open source and proprietary drivers. During the delay, it's just a black screen. Whenever I logout, there is again a ~10-15s delay with the login screen appearing stuck before lightdm allows me to enter my password again. This is ridiculous!
Yes, I could stick with open source radeon drivers but I would like to install Steam and play my Valve collection on the machine. Is anybody else encountering similar issues?
