video probs with redhat 9 on laptop

[ruiner_066]

i jus set my laptop up to dual boot windows xp & redhat linux 9.0 & everything works great, except that something is not right with linux. it seems to run really slow, like all the games that are installed with it are very jumpy, and when i close the lid of the laptop & then open it again, instead of resuming from standby (does it go into standby in linux?) the screen is black, but on the top are all these sort of staticy rainbow colored lines that jump around...like theres just something wrong with the video. when that happens all i can do is restart & then its fine. a friend suggested that maybe the video card hadnt been detected correctly & said i could check in the file /proc/iomem (is that right?) anyways, the name of the card listed in there seems to be right. does anyone know what i could try here? im a pretty big linux newbie, so i dont really know what im talking about, heh. thanks in advance.

its a dell inspiron 600m with the centrino chipset

1.6 ghz, 512 mb ram, mobility radeon 9000 64mb

The radeons have some issues with DRI. I have a R9000 (non-mobility) running slackware and I have to start into runlevel 3 because KDM or XDM will freeze when I logout.

Welcome to NTFS, ruiner_066 🙂
The video issue might be due to the drivers XFree86 is using. Open up /etc/X11/XF86Config in a text-editor and paste the contents of the file here. That should be a good starting point.

Have you checked out http://www.linux-laptop.net/? They have reviews and how-tos on how to get different kinds of laptops running with Linux. I just looked, and there are at least two entries for your laptop.

# To customise the XKB settings to suit your keyboard, modify the

# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"

# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"

# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
