Resolution issue on Acer Aspire One with RHEL 5

n34tsd · 01-27-2009, 08:08 PM

Hi all, recently I installed RHEL 5 on my Acer Aspire One. Everything's working fine except my screen resolution. I can't seem to get 1024x600. The only resolution I got was 800x600.

The graphics driver and monitor was autoconfigured during installation (i810 945GME Intel Chipset).

I tried editing the xorg.conf by adding the Modeline and Modes "1024x600" to the Monitor & Display section respectively but still no luck.

Have anyone here encountered the same issue or know how to solve it? Any advise is appreciated. Thanks!

Did you look at any of the Aspire One how-tos ?

When running under X, the native/optimum resolution is 1024x600 (standard widescreen ratio). The default X11 configuration will give you fonts that are too large for this resolution - You can add the following line to the "Monitor" section of your "/etc/X11/xorg.conf" file:

DisplaySize 195 113

And add the line:

Option "NoDDC"

to the "Device" section.

That sets the resolution to the correct 96 DPI.

If you're using KDM and find that the DPI settings do not take effect, open /etc/kde3/kdm/kdmrc

find the line that reads ServerArgsLocal=-nolisten tcp and change it to ServerArgsLocal=-nolisten tcp -dpi 96

and you need to be using the 'intel' driver not the i810 driver

I downloaded the xf86-video-intel but I couldn't figure out how to install. Tried to google and came across this thread http://www.linuxquestions.org/questi...-1.1.3-623321/

I got the same error as the thread above, stating that xorg-macros was not installed. I downloaded util-macros-1.2.1 and did a ./configure and make install. All I got was

make[1]: Entering directory '/root/util-macros-1.2.1'
make[1]: Nothing to be done for 'install-exec-am'
test -z "/usr/local/share/aclocal" || /bin/mkdir -p "/usr/local/share/aclocal" /usr/bin/install -c -m 644 'xorg-macros.m4' '/usr/local/share/aclocal/xorg-macros.m4'
make install-data-hook
make[2]: Entering directory '/root/util-macros-1.2.1'
rm-f /usr/local/share/aclocal/xorgversion.m4
make[2]: Leaving directory '/root/util-macros-1.2.1'
make[1]: Leaving directory '/root/util-macros-1.2.1'

After this I'm still getting a xorg-macros was not installed error when i try to install xf86-video-intel. Am I missing something?

What kernel is in rhel5 ?

Your problem could be an issue that the kernel in RHEL 5 is not new enough. Due to the hardware in the netbooks you should need a 2.6.26 kernel or newer in order for things to work properly. (including the graphics)

AA1 wireless device is a rather new Atheros wireless chip not supported by Linux kernel until version 2.6.27.
The use of a kernel >= 2.6.28 is highly recommended to get the internal microphone, sound after suspend, and front-speaker automuting working.

and I think you need 2.6.24 kernel for the intel drive to work properly on the intel 950 Graphics chip.

just so you are aware, before you put a lot o effort into this if your kernel is older..

I'm using 2.6.26 on RHEL 5 right now. Do I have to do any compiling of the drivers with the kernel source or any of that sort? I still can't seem to install the intel drivers.
