But switching to X freezes the computer completely.
Please try method (6). It should work perfectly because it is the successor for method (5) and works even without special patches for X. > X from debian sid. > XFree86 Version 4.3.0.1 (Debian 4.3.0.dfsg.1-10 20041215174925 [EMAIL > PROTECTED]) > Release Date: 15 August 2003 > X Protocol Version 11, Revision 0, Release 6.6 > Build Operating System: Linux 2.4.26 i686 [ELF] > Build Date: 15 December 2004 > > > I would like to get X running to, but there are no traces in the logfile > whatsoever to be seen. Pity. First, boot into X and run the following script ONCE: #!/bin/bash statedir=/root/s3/state mkdir -p $statedir chvt 2 sleep 1 vbetool vbestate save >$statedir/vbe To suspend and resume properly, call the following script as root: #!/bin/bash statedir=/root/s3/state curcons=`fgconsole` fuser /dev/tty$curcons 2>/dev/null|xargs ps -o comm= -p|grep -q X && chvt 2 cat /dev/vcsa >$statedir/vcsa sync echo 3 >/proc/acpi/sleep sync vbetool post vbetool vbestate restore <$statedir/vbe cat $statedir/vcsa >/dev/vcsa rckbd restart chvt $[curcons%6+1] chvt $curcons Unless you change your grahics card or other hardware configuration, the state once saved will be OK for every resume afterwards. NOTE: The "rckbd restart" command may be different for your distribution. Simply replace it with the command you would use to set the fonts on screen. > So it seems that my laptop does not fall in any of these categories. Please try my scripts and resport back.
