Resolution issues

darkeye · 2010-01-20 02:55:11

Hello everyone,

I'm just having some issues adjusting my monitor to its maximum of 1366x768. Right now, it can only be adjusted up to 1024x768.

Here is a selection from lspci:

01:00.0 VGA compatible controller: S3 Inc. VT8375 [ProSavage8 KM266/KL266]

Now I was wondering where I could get the correct driver for it, since a google search turns up prosavage_smbus, however, I can't that module in the repos.

Any ideas about what I should do?

Thanks again!
Brad

Try pacman -S xf86-video-savage ;-)

I installed it, using the pacman command, but there was no change in terms of my resolution, or even in the available options. Is there something else I need to do?

You may have to modify your xorg.conf or xrandr (ie. add a new 'mode').

If you're using a xorg.conf, that should go into the Monitor Section with "Mode ... " (see man page).

If you don't have a xorg.conf you may need to add a mode to your xrandr. First check what your current setup allows by typing

$ xrandr

without argument and check what modes you have. If your desired mode is there, simply switch to it by typing (for example):

$ xrandr --output VGA --mode 1024x768

where "VGA" is the name of your screen as per your xrandr output.

If it's not there you have to add a new mode (again see man pages).

I removed my xorg.conf file, and tried to add in the mode manually, but I get an error: xrandr: Configure crtc 0 failed.

I seem to be on the right track now though, since the modes are now present in xrandr, and in the monitor settings, but still the screen resolution will not change. Any ideas?

Why did you remove your xorg.conf? What video card are you using anyway? NVIDIA, Intel, ATI?

darkeye · 2010-01-21 18:10:37

I removed it because I already knew how to use the xrandr commands, and I figured it would be easier to figure out how to do that then modify my xorg.conf

I still have it backed up though, so I can put it back at any time.

As for my videocard, I really have no clue. It was the default chipset that came with this computer, which I got from my school.
The only thing I really know about it is the lspci output that I posted.

It is a really weird issue though, since it seems just about to resize before the crtc fails.

bump for assistance.

Could you please show us the output from 'xrandr'

darkeye · 2010-01-23 02:53:20

Here it is:
Thanks for your assistance!

Try the following:

get a modeline with gtf:

gtf 1366 768 59.9

This will result in an output with something like:

# 1368x768 @ 59.90 Hz (GTF) hsync: 47.62 kHz; pclk: 85.72 MHZ
Modeline "1368x768_59.90" 85.72 1368 1440 1584 1800 768 769 772 795 -HSync +VSync

Then add the new mode:

xrandr --newmode  "1368x768_59.90" 85.72 1368 1440 1584 1800 768 769 772 795 -HSync +VSync

Then add the new mode:

xrandr --addmode default 1368x768_59.90

Then switch to the new mode:

xrandr --output default --mode 1368x768_59.90

See if that works. If yes, you can add those modelines to your xorg.conf to make them permanent.

I got the same error:

I think this thread will be helpful for me as well. I have a new monitor and it's resolution is 1920x1080

I set it with nvidia with that and the correct 60hz frequency.

But I still see some noise on the background and most importantly, the left border is being "cut off" from my windows.
Opera, firefox, tint2 panel all have a slight cut on the left of ~50px or something.

I've tried what you mentioned above:

$ gtf 1920 1080 60

  # 1920x1080 @ 60.00 Hz (GTF) hsync: 67.08 kHz; pclk: 172.80 MHz
  Modeline "1920x1080_60.00"  172.80  1920 2040 2248 2576  1080 1081 1084 1118  -HSync +Vsync

$ xrandr --newmode "1920x1080_60.00"  172.80  1920 2040 2248 2576  1080 1081 1084 1118  -HSync +Vsync
$ xrandr --addmode default 1920x1080_60.00
$ xrandr --output default --mode 1920x1080_60.00 
xrandr: Configure crtc 0 failed

Why did it failed

Also how can one save this to the xorg.conf like you mentioned ?

EDIT: I did some tweaks on xorg.conf and added the values according to some xrandr outputs according to the xorg wiki:

    VertRefresh  60
    DisplaySize 497 285
    Option "UseEdidDpi" "false"
    Option "DPI" "98 x 96"

still no luck, even the mouse goes out of the screen on this invisible left border
