I can install any version of the kernel (tested with 2.4.{23,24}, 2.4.31, and various 2.6.XX > 2.6.8) and the system turns on and boots fine. However, if I go into suspend to ram (which I think is ACPI S3) where the display is turned off -or- I reboot without shutting down first, the display is not re-initialized. The system seems to come back on into a semi-usable state (i.e. if I reboot the kernel seems to boot and the system comes up), but the display remains solid black, so I have not been able to verify this. Come to think of it, I could probably connect the laptop up to my home network and SSH into it after this happens, but I haven't yet done so. My laptop is a Toshiba Satellite 1800 S207 with a Trident XPAi1 video card. If I use the tridentfb driver (at least as of kernel 2.4) at boot time, the screen turns various shades of gold immediately after the kernel loads. Can someone help me debug this issue so that a fix can be written? The problem happens even with a pristine installation of Slackware 10.2 with the default bare 2.4.31 kernel. TIA Mike
