Video Slow using Red Hat 9


I have installed Red Hat 9 on two different laptops (one is an Ispiron 5100 and the other is an old Latitude CPx).

On both of them I experiment a very slow video redraw which I notice when moving windows on the screen. This happens on both laptops and never happens when running windows (dual boot).

I don't have any 3D application so I can only verify the 2D.

Is this due to video card acceleration?
Do I need new/different drivers?
What are the tools I have to check if my card is actually using the hardware accelerations?


Thank you,
Salvio

I'll second this. Video is very slow here.
Machine specs:

PIV 1.4ghz
256mb RAM (209m free)
510mb SWAP (356 free)
nVidia GE Force 2MX

Will more RAM help?

Is your monitor setup correctly?

A friend couldn't bump up his resolution because he didn't have his monitor configured correctly.

Run redhat-config-xfree86 to verrify it's correctly setup or view your XF86Config file.

my Monitor section (/etc/X11/XF86Config)
------------------------------------------------
Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Generic Laptop Display Panel 1024x768"
HorizSync 31.5 - 48.5
VertRefresh 40.0 - 70.0
Option "dpms"
EndSection

you might want to turn down the colors(Depth) to see if it makes a difference
-------------------------------------------------------------------------------------
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 16
SubSection "Display"
Depth 16
Modes "1024x768" "800x600" "640x480"
EndSubSection
EndSection


I recently upgraded my laptop from RH73, and I can't tell any difference in video performance between the two.

I think xine actually runs better under RH9....

hope this helps,
manny

RH9 on a thinkpad A30
cpu MHz : 1132.387
Mem : 393179136
Swap : 510885888

I think it was the nVidia driver that was wrong. I installed the newest one from www.nvidia.com/ and its running a bit more smooth.

Once I install some more RAM, the system should be great.
Thanks.

My Xconfig is fine.

I am running Gnome (using Red Hat 9) and the difference in speed that I notice is compared to MS Windows 2000 and XP running as dual boot.

The problem is that if I drag a window (any window) on the screen, it leaves a "track" on the desktop... once the video refresh completes (1 or 2 seconds) it goes away.

I have tried the drivers from www.xig.com but nothing changed.


Any other thoughts?

maybe because rh9 has a lot stuff to load when moving windows around from desktop to desktop?

i've been running mandrake 9 kde 3, and i'm running rh9 kde3,
display was a lot faster on mdk then in rh, which makes be believe that could be there's too much stuff for x11 to load and (i don't know what it is) we can remove the unwanted one, could be a bit faster?

I have recently noted that while dragging windows on the desktop the CPU gets maxed out.

I still think that it might be related to video the driver.

I am using Gnome which is not easy on resources... I am going to try some changes in the gnome interface to see how much do I gain.

I have tried all possible theme combinations and all of them give poor performance.

I have found an app called "glxgears" which runs a simple benchmark video.

The normal speed (no user interaction) is 112 FPS, when I move the windows it obviously drops (down to 10 FPS)
