Changing Refresh Rate and Screen Resolution under Solaris 10

Basel · 10-27-2005, 09:58 AM

Hi,

How can I adjust the Refresh Rate and the Screen Resolution under Solaris 10? 60 Hz and 640x480 are the only Refresh Rate and Screen Resolution that are available at the moment.

kdmconfig

kdmconfig did not work since the current window size is too small.

Code:

Sorry, current window size (77x23) is too small.
Minimum window size is 80x24. Exiting.

Run kdmconfig from outside the graphic environment.
Better to have the network set too, and a remote telnet session open, that would allows you to take control of the system should things go wrong.

Thanks I managed to set the Xsun but not Xorg since the /etc/X11/bin directory does not exist. Solaris is now set at a higher resolution but I cannot change the resolution yet.
When I right click and select 'Change Desktop Resolution' under gnome I get the following error:
"The XServer does not support the XRandR extention. Runtime resolution changes to the display size are not available."
Why is that?

Why are you looking for a /etc/X11/bin directory ?
I run Xorg without it.

XRandR extension is not supported by Xsun, and neither by Xorg on Solaris 10,
support seems to exist in recent Solaris Express releases though.

Hi
I'm brand new at Solaris, having just installed Solaris 10 (free version) in a VM. I read this thread about changing the screen size/resolution (current screen size is > monitor size), but being brand new I don't know how to "run kdmconfig from outside the graphical environment".

How do you boot into text mode or exit X? Does Solaris support runlevels or something similar to Linux?

thanks for any help.
David

pass the "-s" option (single user mode) to the boot command or run

Code:

/usr/dt/bin/dtconfig -d
init 6 (beware that this command will reboot your machine)

Run "dtconfig -e" when done.

or exit X?

One of

Code:

dtconfig -d
dtconfig -kill

or

Code:

svcadm disable -t cde-login

or (simpler)
Choose text console session in from the session menu in the graphical login screen.

Sure. They are however being obsoleted starting from Solaris 10 and replaced by service milestones. Moreover, there isn't a runlevel/milestone dedicated to running the graphic environment unlike many Linux distributions provide.

Thanks for all the info. This install was using Xorg but I had trouble trying to reconfigure it (says it couldn't find the commands referred to in the earlier posts), so I switched over to SunX and that seemed ok. I could change the screen size, etc., without problem.

Thanks again.

'kdmconfig' is only used to change the settings of a Xsun server; if you have Xorg instead of Xsun, then you have to create the file /etc/xorg.conf using this command:

/usr/X11/bin/Xorg -configure
