Can't get 1280x1024 resolution


I am unable to set up a higher screen resolution. I use an ATi radeon 9200 SE. Here's my xorg.conf:

# NOTE:  This is a NEW IMPROVED version of XF86Config-fbdev that uses the vesa
# driver instead of the fbdev driver.  Thanks to Kenneth Fanyo who pointed
# this out to me. :)

# This XF86Config file is designed for use with the VESA framebuffer.
# This generic interface should work with nearly all video cards
# (although not every card will support every resolution).

# With the new driver, it should no longer be required to have frame buffer
# support in the kernel, or to run it on the console.
#
# Enjoy! :)

# provide a better stack trace in the core dump to aid in debugging

#    Option     "NoTrapSignals"

# Uncomment this to disable the <Crtl><Alt><Fn> VT switch sequence
# (where n is 1 through 12).  This allows clients to receive these key
# events.

#    Option     "DontVTSwitch"

# This allows clients to receive this key event.

#    Option     "DontZap"

# Uncomment this to disable the <Crtl><Alt><KP_+>/<KP_-> mode switching
# sequences.  This allows clients to receive these key events.

#    Option     "DontZoom"

# Uncomment this to disable tuning with the xvidtune client. With
# it the client can still run and fetch card and monitor attributes,
# but it will not be allowed to change them. If it tries it will
# receive a protocol error.

#    Option     "DisableVidModeExtension"

# Uncomment this to enable the use of a non-local xvidtune client.

#    Option     "AllowNonLocalXvidtune"

# Uncomment this to disable dynamically modifying the input device
# (mouse and keyboard) settings.

#    Option     "DisableModInDev"

# Uncomment this to enable the use of a non-local client to
# change the keyboard or mouse settings (currently only xset).

#    Option     "AllowNonLocalModInDev"

# Set the basic blanking screen saver timeout.

#    Option      "blank time"    "10"    # 10 minutes

# Set the DPMS timeouts.  These are set here because they are global
# rather than screen-specific.  These settings alone don't enable DPMS.
# It is enabled per-screen (or per-monitor), and even then only when
# the driver supports it.

#    Option      "suspend time"  "30"
#    Option      "off time"      "60"

# On some platform the server needs to estimate the sizes of PCI
# memory and pio ranges. This is done by assuming that PCI ranges
# don't overlap. Some broken BIOSes tend to set ranges of inactive
# devices wrong. Here one can adjust how aggressive the assumptions
# should be. Default is 0.

# To customise the XKB settings to suit your keyboard, modify the

#
#    Option     "XkbModel"      "pc102"
#    Option     "XkbModel"      "pc105"
#
# If you have a Microsoft Natural keyboard, you can use:
#
#    Option     "XkbModel"      "microsoft"
#
# If you have a US "windows" keyboard you will want:
#
#    Option     "XkbModel"      "pc104"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
#
#    Option     "XkbLayout"     "de"
#
# or:
#
#    Option     "XkbLayout"     "de"
#    Option     "XkbVariant"    "nodeadkeys"

# If you'd like to switch the positions of your capslock and

Hiya

I use a custom resolution on my monitor.

To get a custom resolution on a crt monitor:

Console:

code:

gtf 1200 900 85 -x

This generate's a modeline for 1200 dots wide by 900 dots high for a resolution of 85 vertical refresh rate. Obviously you just put it whatever values you want in lieu of the "1200 900 85" as shown above.

The output of console would be this:

# 1200x900 @ 85.00 Hz (GTF) hsync: 80.33 kHz; pclk: 131.09 MHz
Modeline "1200x900_85.00" 131.09 1200 1288 1416 1632 900 901 904 945 -HSync +Vsync

copy and paste that for your resolution accordingly in to xorg.conf file. note I had to change the uppercases of the H & V to be lower case for it to work now in slackware 11.


here are my respective xorg files.

Under

EndSubSection
EndSection

don't know if you need this, but kde crashes on logout for kde in slackware 11 and under, in suse ubuntu. this works for me, mileage may vary backup first and use at own risk

kde crashes:

change: /opt/kde/share/config/kdm/kdmrc.
you have to add following to the section [X-:*-Core]
TerminateServer=true

I had the same issues with an LCD, but I was only able to get the exact mode that I wanted at by setting things in a very specific way.

Being able to get the proper resolution is especially important in an analogue LCD since your display, especially fonts, will look like crap if you're not running at the optimal, recommended, resolution @ verticle refresh rate. My method will most likely only work on monitors that have good plug and play support so people's mileage may vary depending upon how well their monitor manufacturer sticks to VESA standards.

I had to use the method, that's I'll get to outlining further down, because it wouldn't use the optimal settings for my monitor (1280x1024 @ 60Hz) in spite of setting the usual settings in my XF86Config-4. Originally I tried using the usual settings that generally work:


Code:
Section "Monitor"
   ...
   HorizSync 30-81
   VertRefresh 56-75
   ...
EndSection

Section "Screen"
   ...
   Modes  "1280x1024"
   ...
EndSection
This didn't work in my case. X wanted to use some other video mode in spite of specifying 1280x1024 and giving a proper Hsync and Vsync ranges. The fix to that is the putting the mind bending Modeline in your X config file [xorg.conf | XF86Config-4] like we used to have to way back or to do things in the manner that I am about to outline.

There's an easy way to figure out all the nitty gritty timing related settings (H freq and V freq are really only a few. There is actually many more.) with monitor and vid cards that have good VESA compliance. Using the read-edid package. It gives you two programs. get-edid and parse-edid.

Go to a directory where you want to create a file to contain the edid related info.

Code:
# get-edid > foo (this creates file foo containing the queried monitor info)
# parse-edid < foo
The idea here is that get-edid retrieves monitor information and creates a file that is parsed through parse-edid into a human readable form that can actually be pasted into the XF86Config-4. Remember to be careful about clobbering/overwriting existing files when your run get-edid.

Code:
Section "Monitor"
   ...
   HorizSync 30-81
   VertRefresh 56-75
         Mode    "1280x1024"     # vfreq 60.020Hz, hfreq 63.981kHz
                DotClock        108.000000
                HTimings        1280 1328 1440 1688
                VTimings        1024 1025 1028 1066
                Flags   "+HSync" "+VSync"
        EndMode
EndSection
The part above that is between Mode and Endmode was what I copy and pasted from the output of parse-edid. That is of course going to be different for everyone. So don't copy and paste what I have here. Copy and paste what the output was when you ran parse-edid. (man get-edid for more detail)

IMPORTANT
I would recommend to exercise some caution. The usual cautions about messing with monitor timings apply here. While any fairly modern modern generally usually has safeguard built in to not try to sync beyond their capabilities, it's still probably a good idea to exercise some good judgement just to be on the safe side. The thing here is that it's directly setting many settings that control the alot of various timings besides just Horizontal and Verticle refresh rates. Also, one can't be completely sure that the information being reported by read-edid is 100% correct since some monitors and/or video cards have bugs or aren't good about sticking to standards. That's where your monitor manual comes in handy -- to doublecheck that it seems right.

In my case, the above correlates to following preset timing mode listed in my monitor manual.
Quote:
VESA, 1280X1024
63.981 kHz Horizontal Frequency
60.020 Hz Verticle Frequency
108.00 MHz Pixel Clock
+/+ (H/V) Sync Polarity
Good luck. Hope this helps people whose Xserver is being a PITA and not setting things like they want. X, for quite some time, has become more automatic about things. It really just takes the settings like Horizsync and VertRefresh and uses them as limits, but it will try to figure everything else out on it's own (hence why modeline is generally unecessary, in most cases, these days). Sometimes, with certain hardware, it doesn't seem to figure out things so good. That's when it's necessary for us to get more specific with it. Some people may want to specify things more verbosely in their X config files because they like to tweak things to be as optimal as possible even though X may find a fairly ok setting on it's own.

For those that, what I wrote, doesn't work for (i.e. there monitor doesn't work well with read-edid), then your last resort is to utilize the video-timings how-to. That how-to is considered obsolete, but truly it isn't in all cases.
