Comment 249 for bug 550625

Hi,

I did the same as @Ben Alex on my DELL Latitude E6510.

- Some issues with screen flickering during a minute or so after X has
started, but then OK.
- ARandr recognizes my laptop screen as (null)1 while System >
Preferences > Monitor says it's a Seiko Epson Corporation 15"@1600x900
(16:9) @60Hz which is wrong, the highest res I have is 1440x900@60Hz
but it displays ok
- Resume from suspend simply freezes with some messages concerning a
wrong version of AppArmor for this kernel preventing cache read/write
- I *still* cannot disable the touchpad altogether, but vertical
scrolling works (not horizontal)
- The microphone patch does not work (but that's probably because it's
not the same hardware :p )

Hope this is helpful,
Steven
