Some question about kde3.5, cant get higher refresh rate

cold95 · 12-24-2005, 10:03 PM

i have a few questions so i wasnt sure where to put this. im a little bit of a linux n00b, but get most of the stuff. well lets see. i upgraded to kde 3.5 on my kubuntu install, and now in logout it only give me "end current session". no shutdown restart. another thing is, when i click on end current session it just shuts down x and im loged in console mode. i can type startx and get back to kde. some how it got changed and doesnt go to the login manager. and one other thing is the refresh rate. ive searched this site and others and they say put in the correct h and v refresh rates. but it does have the correct ones and it still doesnt let me go higher than 60hz. i have a brand new samsung syncmaster 930b with default 1280x1024 @ 75hz but i dunno why it wont go higher. if anyone can answer any of my question, thanks for your help.

When you boot are you booting directly to KDE or to CLI?

As far as the monitor check out /etc/X11/xorg.conf
It probably has something misconfigured. I have the same montior, so for a comparison:

if you have a nvidia card you can try something like this in /etx/X11/xorg.conf

Section "Device"
Identifier "nvidiaCRT"
Driver "nvidia"
VendorName "nVidia Corporation"
BoardName "NV11 [GeForce2 MX/MX 400]"
BusID "PCI:1:0:0"
Option "RenderAccel" "true"
Option "VertRefresh" "85"
Option "DPMS"
#Option "IgnoreDisplayDevices" "DFP"
Option "NoLogo" "1"
Option "NoPowerConnectorCheck"
Option "ConnectedMonitor" "CRT"
screen 0
EndSection

I can't change the refresh rate in kde, but it's always 85 so it's ok for me.

cold95 · 12-25-2005, 02:50 PM

yea, i did change kubuntu to log directly into my account, instead of gdm or cli, which ever it usues. but before i changed to kde 3.5 i could end current session go to the login in manager and restartx if i need to. mainly i just want the damn shutdown restart options back. and no i have an ati 9600 xt.

cold95 · 12-25-2005, 05:25 PM

i got the shutdown, restart options back. i changed the runlevel from 2 to 4.
but i still need help with getting the refresh rate higher.

cold95 · 12-25-2005, 05:59 PM

ive tried running "sudo dpkg-reconfigure xserver-xorg" command and setting up everything, but this has happen before and settings got set wrong. then when i restart theres and error and i cant startx, and i can only login in console mode. from console login how can i back up to the back up xorg.conf file?

kak · 12-26-2005, 03:41 PM

to back it up, run the following:
cp /etc/X11/xorg.conf /etc/X11/xorg.conf.old

On the refresh rates, can you post your xorg.conf file ?

cold95 · 12-26-2005, 06:51 PM

here it is.

Okay change:

Identifier"SyncMaster"
Option"DPMS"
EndSection

to :

Quote:

Section "Monitor"
Identifier"SyncMaster"
Option"DPMS"
HorizSync 30-81
VertRefresh 56-75
EndSection

and then restart X.

cold95 · 12-26-2005, 08:34 PM

well i tried what you said, but it didnt work. X windows has an error.

Code:

Fatal server error:
no screens found

now i only got the command line login.

Hmm...the only thing I see different is:

try adding the "Viewport 0 0" to each Display subsection.

Unless the ATI driver doesn't support higher refresh rates in linux?? But that doesn't sound right.

You need to include the Horizonal and Vertical refresh rates in here for your particular monitor.

At least that's the way it is on my slackware box and for my hitachi cm751 19" monitor I have:

HorizSync 31 - 92.0
VertRefresh 55-160

I would post my ubuntu xorg.conf, but I dual boot that with winders 2000, which I'm on right now.

Edit: Of course, I'm old and poor and behind the times...

, maybe the new LCD monitors don't require this info.

Edit2: And, is there really an advantage to running an LCD at a higher refresh rate? I'm just asking, because I don't know.

cold95 · 12-27-2005, 01:37 PM

woot! i got it working, some how. not sure what made it work. but i got 75hz now. here my xorg.conf

i think the only difference is, im using the fglrx driver instead of just ati driver.
and lcd at lower refresh rates you dont really get the flickering but it does hurt my eyes if i look at it too long. now i just need to figure out how to get all the buttons on my logitech mx-518 mouse to work

palceksmuk · 12-27-2005, 03:26 PM

I've got an mx518 and here are my conf. files, but I couldn't get all the buttons to work. It seems that you need to have something special compiled in the kernel to make it work, but when I bought the mouse I didn't want to recompile the kernel. I think it's evdev.

xorg.conf

Code:

Section "InputDevice"
        Identifier  "Mouse0"
        Driver      "mouse"
        Option      "Protocol" "ExplorerPS/2"
        Option      "Device" "/dev/input/mice"
        Option      "Buttons" "9"
        Option      "Emulate3Buttons"    "false"
        Option      "ZAxisMapping" "6 7"
        Option      "Resolution"  "800"
EndSection

somewhere in your x startup scripts:

Code:

xmodmap -e "pointer = 1 2 3 6 7 4 5 8 9" &
imwheel -f -k -b "67" &

cold95 · 12-28-2005, 07:06 PM

damn, i hate to ask this and look stupid but, which file is the x startup scripts?
