I had the same problem with an ibm tp a30 (radeon chip). I also use the
vesa interface for X, and after finding the following in `man
XF86Config-4' I just turned DPMS off, and now it works:
,----[ Option "StandbyTime" "time" ]
| sets the inactivity timeout for the "standby" phase of DPMS mode. time
| is in minutes, and the value can be changed at run-time with xset(1).
| Default: 20 minutes. This is only suitable for VESA DPMS compatible
| monitors, and may not be supported by all video drivers. It is only
| enabled for screens that have the "DPMS" option set (see the MONITOR
| section below).
`----
I still have problems of X dying if I switch to console and back, I am
using the kernel framebuffer (2.4.17pre9)
