How to force X11 resolution and refresh on Slackware 14.0

How can one force X11 to use a mode specified in xorg.conf but not detected ?

Since the introduction of KMS, things seem more difficult, for the end-user.

Here is what I have tried:

My xorg.conf is created by the xorgsetup program.
My display adapter is Radeon HD6550. System loads radeon framebuffer driver at boot which sets 1024x768@60 for all consoles.
X11 runs at same resolution and display.
EDID (/Xorg.0.log) reports several modes, up to 1024x768@60

The fact is that my system is connected to a 2 port KVM and I know for a fact that the setup works at 1024x768@75 because this is the other system's configuration (when in windows).

First problem: probably due to the KVM, but not sure, the video driver detects very few resolutions. I know the KVM is limiting here.

Second problem: following all known procedures to set up xorg.conf with a forced resolution, including all tips found on the net, so far I have failed.

Adding a new mode via xrandr and switching to it at runtime works.

Forcing the same mode via xorg.conf does not.

Here is what I have tried so far :

Section "Monitor"
<------>Identifier "Monitor0"
<------>VendorName "Monitor Vendor"
<------>ModelName "Monitor Model"
<------>HorizSync<----->31 - 82
<------>VertRefresh<--->56 - 75
<------># 1024x768 @ 75.00 Hz (GTF) hsync: 60.15 kHz; pclk: 81.80 MHz
<------>Modeline "1024x768_75" 81.80 1024 1080 1192 1360 768 769 772 802 -HSync +Vsync
<------>Modeline "1024x768@75" 78.750 1024 1048 1144 1312 768 769 772 800 +hsync +vsync
<------>Option "PreferredMode" "1024x768@75"
<------>Option "DPMS"
<------>Option "NoUseBIOS"
EndSection

Mode "1024x768_75" is generated by gtf
Mode "1024x768@75" is generated by PowerStrip on the other windows machine

Some web hints were to add
<------>Option "DPMS"
<------>Option "NoUseBIOS"

Some web hints were to add these to the Device section:
<------>Option "IgnoreEDID" "true"
<------>Option "NoDDC" "true"
<------>Option "Monitor-VGA-0" "Monitor0"

Some hints from the RADEON driver were to add these to the Device section:
<------>Option "EXAPixmaps" "off"
<------>Option "AccelDFS" "off"

Some hints were to add these to the Screen section:
<------>Option "UseEDID" "false"
<------>Option "UseEDIDDpi" "false"

And of course, this:
<------>SubSection "Display"
<------><------>Viewport 0 0
<------><------>Depth 24
<------><------>Modes<-><------>"1024x768@75"
<------>EndSubSection

=====================================================================

None of these worked. X11 stubbornly starts only at 1024x768@60.

This is from the log:

[ 8681.285] (==) modeset(0): DPI set to (96, 96)

=================================================================
However, in fact this still goes to 1024x768@60

and just a bit below:

[ 8681.286] (II) modeset(0): RandR 1.2 enabled, ignore the following RandR disabled message.
[ 8681.286] (==) modeset(0): DPMS enabled
[ 8681.286] (WW) modeset(0): Option "PreferredMode" is not used

==================================================================

I have 3 device sections.
One is with driver radeon
One is with driver modesetting
One is with driver vesa

Only if I add Option "Monitor-VGA-0" "Monitor0" to the card1 device (modesetting), then in the X11 log file I see Output VGA-0 using monitor section Monitor0, otherwise it says it has no monitor section.

Section "Device"
### Available Driver options are:-
### Values: <i>: integer, <f>: float, <bool>: "True"/"False",
### <string>: "String", <freq>: "<f> Hz/kHz/MHz",
### <percent>: "<f>%"
### [arg]: arg optional
#Option "SWcursor" # [<bool>]
#Option "kmsdev" # <str>
#Option "ShadowFB" # [<bool>]
Identifier "Card1"
Driver "modesetting"
BusID "PCI:1:0:0"
Option "Monitor-VGA-0" "Monitor0"
EndSection

I have tried combinations and combinations, I am probably missing something, but I can't make it start with 1024x768@75, I can only change with xrandr at runtime to that resolution.

Thank you.

What happens if don't use an xorg.conf?

To check, please get rid of it.

For instance. "mv /etc/X11/xorg.conf /etc/X11/xorg.conf.save" then (re)start X and post you full X log (either use pastebin or as an attachment with the .txt extension)

You should not be using the modeset driver, but the radeon driver. Where did you get that xorg.conf from?

Try appending
Code:
video=VGA-1:1024x768M@75
to the kernel command line.

It was generated by xorgsetup utility.

Is that "VGA-1" ? (I'm only asking because the VGA output is named VGA-0 in the X11 logs).

Second, 1024x768@75 exists (at this time) only in xorg.conf but not in fb.modes.
There is a 1024x768-75 there, but mine was tweaked with timings identical from both systems connected to the KVM.

I will try to add 1024x768@75 with my timings to the kernel command line.

You'll want to fix it then so that it uses radeon.

Yes it is.

KMS video outputs have nothing to do with Xorg video outputs.

KMS doesn't use /etc/fb.modes and made it obsolete.

You should use VESA Coordinated Video Timings (CVT) on all systems with video=VGA-1:1024x768M@75 (notice the "M"?)

KMS doesn't support custom modelines.

Video device 0 in xorg.conf should be set to the radeon driver.

Change this line in your xorg.conf to reflect as such:

Code:
Identifier "Card0"
Driver "vesa"
Change to

Code:
Identifier "Card0"
Driver "radeon"
Restart X-Server and all should work well.

If you need a refresh rate tool, download, build, and install "driconf" from SlackBuilds.

Finally, I located this info in /usr/src/linux/Documentantion/fb/modedb.txt
Thank you for the help, I don't think I would've found it by myself.
From what I read there, the timings are either probed, or from a table (which is hardcoded).

When I try to set timings in the console with fbset, I get this:
Code:
~# fbset -pixclock 12698
ioctl FBIOPUT_VSCREENINFO: Invalid argument
(in fact, any video mode in fb.modes can't be set with fbset, with same error).

Actually, fbset shows nothing for timings :

Code:
:~# fbset

mode "1024x768"
    geometry 1024 768 1024 768 32
    timings 0 0 0 0 0 0 0
    accel true
    rgba 8/16,8/8,8/0,0/0
endmode
Also, fbset -move does not work

I added the kernel command line as suggested, and my console is now 1024x768 75Hz (although not with the timings I would like). I can't set anything (except virtual resolution) with fbset.

I generated a new xorg.conf file (using xorgsetup) just to make sure I start clean.
I commented out the 2 driver sections about "vesa" and "modesetting" and the corresponding monitor and screen sections.
I customized my monitor0 section to use my modeline.

Code:
Section "ServerLayout"
        Identifier     "X.org Configured"
        Screen      0  "Screen0" 0 0
#       Screen      1  "Screen1" RightOf "Screen0"
#       Screen      2  "Screen2" RightOf "Screen1"

The problem is the same: monitor starts up in 1024x768 60Hz.

This is what xrandr reports:
Code:
xrandr
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 16384 x 16384
VGA-0 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1024x768@75    75.0 +
   1024x768_75    75.0
   1024x768       60.0*
   800x600        60.3     56.2
   848x480        60.0
   640x480        59.9
HDMI-0 disconnected (normal left inverted right x axis y axis)
DVI-0 disconnected (normal left inverted right x axis y axis)
but, a later run of xrandr
~$ xrandr --output VGA-0 --mode 1024x768@75
will set the display to the mode I want and the refresh I want.

I still can't figure out what can I do in the config file xorg.conf so that X will start in the proper mode.

Remember what jtsn wrote:
Quote:
KMS video outputs have nothing to do with Xorg video outputs.
So just append this line
Code:
append = "video=VGA-1:1024x768M@75"
to the proper lilo.conf's stanza and you're all set. You don't need an xorg.conf at all unless maybe for other specific settings.
