Hi folks,
Having power down issues with my system and monitor on shutdown of Mandriva 2006. My computer isn't new - My monitor is a Generic Targa 17'', I have the Riva TNT2 graphics card - though no visible issues with graphics/display while running Linux, and Mandriva does detect both of these.
When I first installed Mandriva 2006, Mandriva would shut down correctly, EXCEPT the system wouldn't power down (monitor black but everything switched on). This happened when setting "enable ACPI" to ON. I ballsed up Mandriva with Ubuntu install, so now I've reinstalled it again.
On reinstall, I disabled this option. Now what happens is quite strange: The first thing I noticed now, is that whenever I reboot or log out, my monitor very briefly shuts off, and i get that quick "no signal or cable disconnected" message on my monitor, but then everything comes back up again fine. On shutdown, my system itself WILL shut off BUT the monitor wont, and starts rolling through colour flashes on the screen (i.e screen goes red, then blue, then green etc). I've never seen such a thing. I also went into the boot option and put "enable ACPI" back on, but the colour thing is still there.
The same thing happens when I boot to Windows XP Pro, and shut down through that interface. I can only remedy it by turning the monitor off at the power point.
Btw, so you know, I'm a total Linux newb (talking, a few days here). I'm also writing to you through Windows, because the 3 Lin distros I've installed won't read my winmodem (which may I say, is really disappointing - but that's another saga). I've found a few sort of related posts, but I didn't understand them - too much assumed knowledge hehe
Please try and be patient with me; you may have to go into more detail about where/how exactly I type in the commands or what have you. Thanks very much
