Xorg seems to be using an inordinate amount of cpu power for relatively simple 2D graphics ops
For example, moving one text-only gterm over another (back-and-forth) cause Xorg cpu usage to spike from 2.7% to 20%. Running a gterm over the mythfrontend menu page, causes Xorg cpu usage to spike to 50%. Scrolling a google search results page rapidly (text only) in Firefox also spikes Xorg CPU usage to 50%
Of course, situation gets worse when I do more 2D intensive graphics like playing back an HD quality mpeg2 video -- Then cpu usage spikes to 50-60% for Xorg and 40-50% for the player.
Is something wrong here?
While my card is relatively old, I still would think that it shouldn't have that much problem with redrawing simple xterm text windows.
My setup is as follows:
GeForce Ti 4600 with 9633 drivers
Intel P4 2.8 GHz CPU on an ASUS p4pe motherboard
2 GB DDR RAM
Fedora Core 6/Linux 2.6.20 with Gnome
I have tried turning on/off various settings under nvidia-settings including sync-to-blank and cursor shadows.
My Xorg.conf has the following (relevant) settings:
Section "Files"
ModulePath "/usr/lib/xorg/modules/extensions/nvidia"
ModulePath "/usr/lib/xorg/modules/extensions"
ModulePath "/usr/lib/xorg/modules"
EndSection
Section "Module"
Load "glx"
Load "extmod"
EndSection
Section "Device"
Identifier "Videocard0"
Driver "nvidia"
# Driver "nv"
VendorName "LeadTek/NVIDIA"
BoardName "NVIDIA GeForce4 (generic)"
#JJK Additions:
Option "NvAGP" "3"
Option "RandRRotation" "True" # Enable rotation via: xrandr
Option "AllowDDCCI" "True"
Option "Cursor Shadow" "True"
EndSection
Any ideas on what might be going on or is this "normal"?
