Dell Inspiron 4150 monitor goes on fritz when lid closes
I have redhat 9.0, 512mb ram, 30gb hd, 2000mhz, and a dell inspiron 4150.

For some reason whenever I load up linux, and decide to close the lid of my laptop (lower the monitor so it looks thinner... side view -> _ not L ) when I reopen the lid of my laptop, the screen is cut in half and makes the screen an unreadable static. In redhat 8.0 i updated my kernel and i could close and open my laptop fine, but in 9.0 only sometimes I can reopen my laptop without having this problem. It is very wierd, maybe 1/10 times i can open my laptop and have a normal screen otherwise it is all static and I have to reboot.

can anybody offer a solution?:cry:

Assuming you're using the X window system, have you tried using ctrl+alt+F1 to switch to a text console when the screen has fuzzed? Does this work? Also, ctrl+alt+backspace will kill X, which will then be restarted if you're using a session manager such as kdm or gdm - this may correct the situation without a full reboot.

This could very well be an issue related to kernel power management. What do you mean by saying that you upgraded your kernel in redhat 8.0? Was this a new compilation, or a download from redhat? If this issue is very serious for you, you might try experimenting with the various power management options in kernel configuration.

Ok, im going to update my reply on restarts...

When I did CTRL + ALT + F1 it does get me to the text mode, but how do I get out of the text mode and back to the Gui setup? By working I mean, it still is "frizzy" but it goes to the text mode. I can't make out any words, but I can type everything in. When it gets "frizzy" the computer doesn't freeze but it just looks screwed up.

CTRL + ALT + BACKSPACE works just like going into the text mode, meaning it does quit X succesfully, but it still is a fuzzy half screen that isn't clear/visible.

Gui is normally at CTRL+ALT+F7 and should start itself again after the Backspace thing.What graphics setup do you got?

Here are my graphic settings:
-KDE System
-Unprobed Monitor (50-70 refresh rate)
-ATI Radeon Mobility 7500
-Color Depth - Millions of Colors
-Resolution 800x600 (but I changed to 1024x768, and it switched back for some reason)

my girlfriend just got a lappy with the same graphics card as yours. She is running Suse and I need to get the graphics card working for her.

What did you find the graphics driver?

all help will be greatly apreciated.

my dell was customized.. so i have the 32mb video card

But when I popped in the cd's my video was working perfect, my only problem is when I close the lid and open it up.. i don't get that..

but in the control panel you can set up a kde theme, and there are other preferences there, but for some reason the settings don't ever work for me (they never apply) so I think that's why I have my problem. but you can probably fix yours just by messing with the settings there and hoping they will apply when you press ok
