Thread: Display freezes after boot


hello all,

upgraded 12.04 lts 12.10 old acer aspire 5600
12.04 lts did work good

12.10 after boot display freezes (horizontal , vertical lines) => thought bad ram => checked via memtest (the display shows without lines, should be)

result : memtest 4.20 #7 gives me on each ram-stick complete red error-lines

=> why there no problem on 12.04 lts?
=> ram-sticks corrupted?

kindly awaiting ideas
