what does

xrandr -q

show now with edid turned off?

Re: KDS Monitor / "RV530LE [Radeon X1600]" graphics card - high resolution problems

Okay....

My monitor specs are as follows 1280x1024 / 85Hz, 1600x1200 / 65Hz per this site http://www.kdsusa.com/XF9s.asp ....... am I up the creek because Radeon has 80kHz vs 85Hz and 75Hz vs 65Hz for the same resolution ? Cry

Or is there something else I can try

[scotter59]

Re: KDS Monitor / "RV530LE [Radeon X1600]" graphics card - high resolution problems

Found this http://lxr.linux.no/#linux+v2.6.35/d...rm/Kconfig#L54 it has the following in it:

#
# Drm device configuration
#
# This driver provides support for the
# Direct Rendering Infrastructure (DRI) in XFree86 4.1.0 and higher.
#
 
config DRM_RADEON
    tristate "ATI Radeon"
    depends on DRM && PCI
    select FB_CFB_FILLRECT
    select FB_CFB_COPYAREA
    select FB_CFB_IMAGEBLIT
    select FW_LOADER
    select DRM_KMS_HELPER
    select DRM_TTM
    select POWER_SUPPLY
    help
      Choose this option if you have an ATI Radeon graphics card. There
      are both PCI and AGP versions. You don't need to choose this to
      run the Radeon in plain VGA mode.

      If M is selected, the module will be called radeon.

source "drivers/gpu/drm/radeon/Kconfig"

If this would help, where would I put this ?

Re: KDS Monitor / "RV530LE [Radeon X1600]" graphics card - high resolution problems

I wish I could help but I'm not an ATI guy.

You can manually create and force resolutions with xrandr

**WARNING** forcing your monitor out-of-spec can damage your hardware - use extreme caution!

  1280x1024   75.0 
  1024x768    85.0*  85.0   75.1

This shows 1024x768@85 is your current default. To add and use a new mode at 1600x1200@65, open a terminal and type these commands:

xrandr --newmode "1600x1200" 176.23 1600 1712 1888 2176 1200 1201 1204 1246 -HSync +Vsync

xrandr --addmode VGA-0 1600x1200

xrandr --output VGA-0 --mode 1600x1200

This will immediately switch you to the new mode. I'd keep my finger on the OFF button of the monitor just in case it can't take it (whistles or buzzes loudly).

It's possible your monitor or card just won't do this resolution with linux. Have you tried any other distros?

[scotter59]

Re: KDS Monitor / "RV530LE [Radeon X1600]" graphics card - high resolution problems

So that is how xrandr works.....cool, tried some examples but did not do the "--output", since my attempts did not appear to work I was not sure if it applied to my situation. Like reading about xorg.config, it is used or not, if not what is....

xrandr did jack the resolution to what I would want but it was not the solution I wanted. Felt like I was on an ocean, everything waved, at least I could see something besides black screen to shutdown.....

.....but I might experiment some now that you showed me how to make xrandr work.

Did you use a tool to compute the newmode line, how about for 1280x1024 resolution, that would beat the current 1280x768. My Xorg.0.log has 75 KHz for

"1600x1200"x0.0 162.00 1600 1664 1856 2160 1200 1201 1204 1250 +hsync +vsync (75.0 kHz)

Will try....

xrandr --newmode "1600x1200"x0.0 162.00 1600 1664 1856 2160 1200 1201 1204 1250 +hsync +vsync


xrandr --newmode "1280x1024"x0.0 135.00 1280 1296 1440 1688 1024 1025 1028 1066 +hsync +vsync

Did try the live CD of Mint but it took me down the same path.....

Thanks again for the assistance.

Re: KDS Monitor / "RV530LE [Radeon X1600]" graphics card - high resolution problems

Thought it worked till I tried to do something, Kubuntu application launcher or other windows and the waves came back.....

Tried the following based on the Xorg.0.log values......
1600x1200

xrandr --newmode "1600x1200"x0.0 162.00 1600 1664 1856 2160 1200 1201 1204 1250 +hsync +vsync
xrandr --addmode VGA-0 1600x1200x0.0
xrandr --output VGA-0 --mode 1600x1200x0.0

1280x1024

xrandr --newmode "1280x1024"x0.0 135.00 1280 1296 1440 1688 1024 1025 1028 1066 +hsync +vsync
xrandr --addmode VGA-0 1280x1024x0.0
xrandr --output VGA-0 --mode 1280x1024x0.0

The monitor frequencies do not match what is coming out of Xorg.0.log or xrandr -q......

My monitor specs are as follows 1280x1024 / 85Hz, 1600x1200 / 65Hz per this site http://www.kdsusa.com/XF9s.asp ....... am I up the creek because Radeon has 1280x1024 80kHz vs 85Hz and 1600x1200 75kHz vs 65Hz for the same resolution ? Though the KDS site specifies Hz vs kHz.......

So close, learning about X server, thanks,
Scott

Re: KDS Monitor / "RV530LE [Radeon X1600]" graphics card - high resolution problems

The command line tool for modes is gtf.

Type gtf 1280 1024 65 and you get 1280x1024@65hz modeline.

This page has a detailed explanation of modelines and how to adjust them

http://www.arachnoid.com/modelines/

I had a media computer hooked to a 50" plasma and I ended up manually manipulating the modeline until I got the picture I wanted.

[scotter59]

Re: KDS Monitor / "RV530LE [Radeon X1600]" graphics card - high resolution problems

gtf 1280 1024 65

# 1280x1024 @ 65.00 Hz (GTF) hsync: 69.10 kHz; pclk: 119.40 MHz
Modeline "1280x1024_65.00" 119.40 1280 1368 1504 1728 1024 1025 1028 1063 -HSync +Vsync

xrandr --newmode "1280x1024_65.00" 119.40 1280 1368 1504 1728 1024 1025 1028 1063 -HSync +Vsync
xrandr --addmode VGA-0 1280x1024_65.00
xrandr --output VGA-0 --mode 1280x1024_65.00

This worked !!!!
Will try the same process for the 1600x1200 resolution.....

Way cool, thanks for the assistance "oshunluvr".

I take it that this modeline can be added to the screen section of xorg.conf with no change ?

[oshunluvr]

Re: KDS Monitor / "RV530LE [Radeon X1600]" graphics card - high resolution problems

Should work that way - if not post back, you can set it up so xrandr commands are run at log in if need be.

[scotter59]

Re: KDS Monitor / "RV530LE [Radeon X1600]" graphics card - high resolution problems

Should - not - "xorg.conf" did not play well with the new modeline, turned the monitor off.
So where is the correct location for this xrandr script, assume one of the rc0.d to rcS.d...

I nearly managed to get 1600x1200 working with the following:

gtf 1600 1200 61

 # 1600x1200 @ 61.00 Hz (GTF) hsync: 75.82 kHz; pclk: 163.78 MHz
 Modeline "1600x1200_61.00" 163.78 1600 1704 1880 2160 1200 1201 1204 1243 -HSync +Vsync

xrandr --newmode "1600x1200_61.00" 163.78 1600 1704 1880 2160 1200 1201 1204 1243 -HSync +Vsync
xrandr --addmode VGA-0 1600x1200_61.00
xrandr --output VGA-0 --mode 1600x1200_61.00

but the video starts degrading at the top right.....

I also tried the liveCD of SuSe and its gui change window had the same issues....did not feel like redoing this Kubuntu installation yet, had it less than a year.

Again thanks for the lesson and the territory......

Re: KDS Monitor / "RV530LE [Radeon X1600]" graphics card - high resolution problems

You should look into your log file after a failed boot - /var/log/Xorg.0.log or Xorg.0.log.old and see what it has to say.

I believe to "correct" way to invoke xrandr at session start is to put a file with your commands into /etc/X11/Xsession.d and make it executable.

[scotter59]

Re: KDS Monitor / "RV530LE [Radeon X1600]" graphics card - high resolution problems

I put the xrandr script in:

/etc/kde4/kdm/Xsetup

https://wiki.ubuntu.com/X/Config/Res...rtup%20scripts

The logon is off center, but I can deal with that....

Thanks again for the assistance

Re: KDS Monitor / "RV530LE [Radeon X1600]" graphics card - high resolution problems

I have screen territory now which is great

However when I try to play a Microsoft game on an XP guest on VirtualBox the graphics get hosed. I tried the game also (Rise of Nations) on Wine, believing that VirtualBox may have caused the problem.

Did not have time to start the log hunt again ..... so I have territory and basic usage the machine is functional, even windows on VirtualBox is satisfactory. A 3GL screen saver on VB/XP will result in 32bit regression to 16 bit error message and Microsoft RTS games do not function well.

I assume the purchase of a monitor would that fit with the video card specs displayed by "xrandr -q" would resolve this issue.

[Snowhog]

Re: KDS Monitor / "RV530LE [Radeon X1600]" graphics card - high resolution problems

However when I try to play a Microsoft game on an XP guest on VirtualBox the graphics get hosed.

Games, run in a virtual machine, use a 'virtual' graphics card, not the real card. As such, the full features of the real card are not emulated, and games that require 3-D capability don't work well, if at all.
