Comment 26 for bug 235284

@gertvdijk, thanks for answer
Did it exactly as per (http://www.thinkwiki.org/wiki/Install_Ubuntu_Hardy_Heron_on_a_T61p):
Lenovo T61p 6457-C65, newest Bios (ver. 2.21, 2008-07-01), fresh installed Ubuntu 8.04 64bit, newest nvidia drivers installed with "Envy", modification of /usr/share/hal/fdi/information/10freedesktop/20-video-quirk-pm-lenovo.fdi, reboot and then Fn+F4 to test. Suspend works but Resume not. Just get a black screen with a blinking cursor in the upper left.
Any suggestion where to start the debugging?
Do anyone else have it worked out on a 6457-C65?
