Re: Problem with resolution on Radeon HD 7459 card (Squeeze)

[Han Soo Chang <hansoo77jp@gmail.com>]

Thanks again for your help.

I didn't realize that I needed to install xorg from the backports
besides an upgraded kernel
and fglrx driver.

Now, I installed linux-image-3.2.0-0.bpo.1-amd64, xorg, fglrx-driver,
and fglrx-control
from the squeeze backports.

# aticontrol --initial again failed to recognize my graphic card.

So I made a small /etc/X11/xorg.conf file with following content.

---
Section "Device"
 Identifier "ATI"
 Driver "fglrx"
EndSection

Section "Screen"
 Identifier "Default Screen"
 DefaultDepth 24
EndSection
---

Now, I get the desired resolution of 1920 x 1080.

However, redrawing of windows is very slow, and I can't move a window smoothly,
which is quite bothersome.

gnome reports that my refresh rate is 60 Hz.

I feel I am almost there, but I don't know if this problem is remediable.
Perhaps, some additional lines in my xorg.conf file?
