How to get widescreen resolutions?

Recommended Posts

I'm using Mandriva 2007 with xrandr 1.0. Typing xrandr gives only 3 modes: "1024x768" "800x600" "640x480". In previous Mandriva 2007 installations I did have widescreen options in the Mandriva Control Center but now I only have 4/3 ones & only 16 bit depth.

 

I added 1600x900 & 1600x1200 modelines to xorg.conf. If I add "1600x900" or "1600x1200" to the first line of the 8,15,16,24 depths, it goes into a distorted 640x480. 1280X1024 is the highest resolution it can produce.

 

I'm using onboard VIA graphics & the HP 2009v monitor.

Is there any special reason why you are using such an old version of Mandriva?

 

I'm asking because you might likely find that a newer version will handle this better and therefore save you a lot of config fiddling.

I think you may be using the VESA driver instead of the VIA (openchrome or unichrome) driver.

I agree with theYinYeti. Please post the output of

grep -i driver /etc/X11/xorg.conf

so we can see what driver you're using.

Yes it is using vesa.

 

In fact my motherboard is asus k8v-vm but I can't find any Linux display driver for it.

 

I don't know how to correct the /var/log/Xorg.0.log

Xorg.0.log is not something to be fixed, it's a log file. Earlier this year I had problem similar to yours. While examining my Xorg.0.log I saw an error message, something about can't read monitor EDID data, and something about defaulting to certain display resolutions. I don't recall the specifics, but it lead me towards a solution.

 

Probably there's no driver specified for the Asus k8v-vm, however you can use the command line utiliy 'lspci' to see which 'VGA compatible controller' has been identified.

 

If you have a recent Mandriva live CD you can try booting that and see if that allows the wide screen display. If it does, find which driver is being used.

I did lspci & it says VIA.

 

I downloaded the VIA S3 Chrome9 HC Linux Display Driver but can't make sense of the instructions(attached). One line says:

 

Mandriva Linux 2007.0 will have the kernel source tree in /usr/src/

folder when installing the kernel source rpm package

"kernel-source-2.6.17.5mdv-1-1mdv2007.0".

 

Also:

5. Use a script to build VT3336-3364XORG40079 driver and select the

"79" version and CPU type to build. The driver binary will be created

in default /VT3336-3364XORG40079 folder.

# tar zxvf VT3336-3364XORG40079-kernel-src_[date].tgz

# cd VT3336-3364XORG40079-kernel-src_[date]/src

# ./makedriver drm (Other distributions only build 2D/MPEG driver)

 

What does it mean?

What about the dependency packages?

It seems so complex.

I don't know much about compiling drivers from source code.

 

Are you sure there's no via driver in your Mandriva 2007? At the moment I'm using 2010.0, and there seems to be a via driver located in

/lib/modules/2.6.31.13-desktop586-1mnb/kernel/drivers/video/via/

 

By the way, I think support for 2007 has been dropped. If so, then you are not getting security patches and bug fixes.

Hello Prost.

 

This is only a question of curiosity and should not be taken to imply a criticism of any kind.

 

Just why are you still persevering with 2007 when Mandriva has advanced so far.

I remember even 2008 was superior and rock solid at least ???. Have you tried more recent releases, e.g. 2008.0, 2008.1, 2009.0, 2009.1, 2010-0, 2010-spring ???.

If you did , what sort of problems did you have ???. If your problem is not having good access to downloading ISOs then I can fix that for you very quickly by posting a DVD of 2010-spring (or earlier ones if you choose) to you by Air Mail quick smart.

 

Cheers. John.

I figured out how to install the via driver on 2007. One problem was that a few files were missing. I can get 1440x900. If I try 1600x900 the screen scrolls when I move the cursor to the end. I don't know why I can't use more than 1440x900. The PC does crash.

 

The openchrome driver didn't work. I did read that bug page you posted. I could select the driver in the Mandriva Control Center but the PC can't enter gui.

Please post the output of

egrep 1600x900 /var/log/Xorg.0.log

 

Using google, I haven't found anyone that has successfully used a 1600x900 resolution with the openchrome driver at this time.
