Mandy 10.0 Video/Display Issues


hello all,

i am running mandrake 10.0 official on an older PII-333, with 128mb of ram, and a 6gb hard disk. there is no other o/s installed. i've searched google, this forum, and a few other places for help, and can't find a solution.

here's the issue:

when KDE loads, the desktop is enormous, and only 60% of it or so fits on my screen. i can't see the taskbar (kpanel?) at the bottom of the screen, and most windows open almost entirely off-screen.

there is also a weird wrapping effect. if i move my mouse (or a window) to the left edge of the screen, it wraps around and shows up on the right edge!

i don't know what to call this other issue, but basically there's a screen redrawing/refresh issue, or maybe a ghosting issue is more what i'm experiencing. when i move windows around, they leave "ghosted" trails of themselves behind, and cover other things up with all this garbage.

this all seems like a display/video card/monitor driver type issue, but i don't know how to proceed.

ps- I just typed this message a few minutes ago, but my session must have timed out before I hit "preview". perhaps the board should be setup to avoid losing a message when this happens, especially where I was logged in? couldn't it save the typed message in my profile so I don't have to retype it?

KDE Control center -> Peripherals -> Monitor:
Change the resolution to the actual resolution X is running and apply. This is the so called virtual desktop and it can be also disabled in xorg.conf.
You should also select the option to automatically apply this change when KDE starts.
As for the trails, Iīve experienced such problems with several graphic cards in both Linux and Windows. The problem is somethimes too high clock settings, or not properly working driver. Please post your videocard id to see if we can be helpful.

that's great iZvi, thanks, i'll try that. one question before i do: how do I find out what resolution X is running at? i haven't changed anything, so it should be the default for mandrake 10.0 if there is a default. is the resolution X is running at in a config file somewhere?

thanks again,

dan

ps- i'll post my video card details in a bit, i have to dig around for the documentation. there's probably a way to figure it out from within linux, but whereas i have no clue what i'm doing, i don't know how!

Hmm I always recognise the resolution by the size of the things, and I donīt need an utility to see it, however try xvidtune,(In xterm or Konsole type xvidtune) , it will display your resolution settings. Look for HDisplay and VDisplay. Then exit with quit. It can also change the resolution but if you change it with this, the virtual desktop will remain.
If xvidtune doesnīt work or shows the virtual size, just experiment with the KDE resolution settings to find the best for you.

For the videocard, nothing special, only the vendor of the chipset (nvidia geforce, Riva, Ati and the driver loaded for it).
KDE Information Center -> PCI:
Find which device looks like a video card (assuming your vc isnīt ISA ). There should be more clever way, but Iīm not an expert so thatīs what I can suggest.

one problem: i can't find "KDE Control center -> Peripherals -> Monitor:" because the screen is so ridiculously big that i can't see anything. is there a key combination to get to it if i can't see it? i can get a terminal window, i can open konqueror, but i don't have the taskbar at the bottom for other normal tasks. any ideas?

update: i was able to browse the hard disk until i found kcontrol.exe, that did the trick. changing the resolution also fixed the ghosting issue. i will probably have a ton more questions, but now at least i have a usable desktop and don't have to switch to my windows box to google for solutions!

thanks so much iZvi. Your help is much appreciated.

Dan
