Cant add resolution 2 monitor xrandr

In terminal trying to add with cvt

cvt 1360 768

1360x768 59.80 Hz (CVT) hsync: 47.72 kHz; pclk: 84.75 MHz

Modeline “1360x768_60.00” 84.75 1360 1432 1568 1776 768 771 781 798 -hsync +vsync

xrandr --newmode “1360x768_60.00” 84.75 1360 1432 1568 1776 768 771 781 798 -hsync +vsync

xrandr --addmode DVI-I_2/digital “1360x768_60.00”

X Error of failed request: BadMatch (invalid parameter attributes)

That’s a HDTV, right?

What’s the EDID info in /var/log/Xorg*.log? The preferred mode should be there.

On my laptop PC (on openSUSE-11.1 with proprietary ATI driver for an ATI radeon3450 under KDE-4.3.2), typing “xrandr -q” (with external devices plugged in) gives the preferred mode (and all the resolution choices): Laptop External Monitor Support - openSUSE Forums
… this was for an external projector, but I assume HDMI to a HDTV would look similar.

Heres what i wanna do: VGA_1 1680x1050 DVI-I_2/digital 1360x768

As u can see i have 1680x1050 on the VGA_1 screen but i want to have it when i login/out .Now i have to do the (cvt 1680 1050) in terminal and then use the xrandr --newmode xrandr --addmode

And that works fine for the VGA_1 but not the DVI

You can also see that the mode is possible because bin bash:answers the cvt 1360 768 question.
Ok i think i go to the /etc/x11/xorg.conf and add the resolution 1680x1050 in a modeline, then i see no xorg.conf file there…
So how do i add the modes for all users login/out…

Im sorry for making this to more questions but this is what i wanna do im gonna search for the EDID info in the var/log file but i haved this resolutions before with FGLRX in ubuntu but in new to open suse and i wanna try using xrandr.

xrandr -q
Screen 0: minimum 320 x 200, current 2960 x 1050, maximum 3840 x 1920
DVI-D_1 disconnected (normal left inverted right x axis y axis)
VGA_1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1024x768 60.0
800x600 60.3
640x480 59.9
1680x1050_60.00 59.9*
DVI-I_2/digital connected 1280x720+1680+99 (normal left inverted right x axis y axis) 160mm x 90mm
1280x720 60.0*+ 50.0
640x480 60.0
DVI-I_2/analog disconnected (normal left inverted right x axis y axis)

From what I can see, 1280x720 is the maximum your DVI supports.

Heres my setup in windows this is what i wanna have using xrandr the mode is not there by default in randr same as the 1680x1050 on VGA_1 thats why it isnt there or?](

Second screen is samsung 32

I don’t know the 1st thing about windoze. My last windoze at home was win95.

Still if you believe windoze can get you the higher resolution for this hardware, and you do not see the option (with xrandr -q ) in Linux, then maybe you need to use a different graphic driver in Linux?

Which graphic driver are you using in Linux ? openGL ? Proprietary ATI ?

Well i dont know

ATI HD Radeon4650 is gpu

default systemdriver Gnome desktop

Try typing this to see if it tells you what graphic driver:

/usr/sbin/hwinfo --gfxcard | grep Driver

Now i am back on the ATI-Driver “fglrx_pci”

So here is the reason why i started this topic with fglrx driver
my desktop can not get 1680x1050 because AMD/ATI has not added the possibility to disable the EDID option who you can do windows version.

But with this fglrx driver i can get the 1360x768 on my secondary screen but im stucked with 1400x1050 on my desktop.

how do i remove xorg.conf files from /etc/x11/xorg.conf because yesterday fglrx didnt work (seems to be an bug maybe you have to turn comp off to disable vesa driver?)and i got like 4 xorg.conf

sudo remove didnt work for me

thx for help…

I don’t have time to review your entire post, but wrt xorg.conf, I actually recommend you do NOT completely remove xorg.conf, but rather just move it some where. You can do that with:

su -c 'mv /etc/X11/xorg.conf /etc/X11/xorg.conf.mybackup'


mv /etc/X11/xorg.conf /etc/X11/xorg.conf.mybackup


su -
mv /etc/X11/xorg.conf /etc/X11/xorg.conf.mybackup

when prompted for a password, enter root password. ONLY use one of the above methods (not all 3).

Maybe i wasnt clear.
Im not gonna remove xorg.conf im gonna remove the backups…
