I've been thinking about a DSL HD install on a 1997 vintage HP Kayak desktop. Before going through the pain of partitioning the HD, I've been testing things out using the DSL floppy/USB install.

The PC has a matrox millenium II agp graphics card. If I leave the PC for a while, it appears that some sort of monitor/graphics card energy saving kicks in - the screen goes blank and will not come back on.

I tried "xset s off off" to turn off any screen blanking with the result that, after a period of inactivity, the system freezes with the display still on.

If I try "xset q", apart from stating that the screen blanking is off, there is a message that DPMS is not enabled/available (or something like that)

I am using the default DSL X windows, is there way to either use or disable DPMS with this?

If you want to turn power saving features off, leaving dpms disabled should be right. Run just `xset` for all the instructions. You may want to use some of those fb video setups - which have fixed some people's problems that have similar problems to this (and check/disable apm/acpi).

It seems you cannot turn DPMS off in the DSL X setup, the DPMS extensions are not included.

I've being trying to disable apm using the boot option "noapm" - whilst booting, I get a message stating apm BIOS detection is being skipped but the module is still loaded. Once the apm module is loaded, I am unable to unload it with rmmod - there is a message stating the device or resource is busy.

Stopping apm might not be the answer, but I'd like to try it to see if the monitor still locks up - any ideas on how to prevent the apm module loading or unload it once loaded?
