Screen rotation

[doosjuice]

I am now satisfied I can work from my kubuntu based machine. I have been setting everything up on a std monitor.

My production monitor is an asus widescreen which I rotate 90 degrees (it supports this feature) so I end up with a tall narrow monitor rather than widescreen.

I just changed monitors to see if any sort of menu appears, it doesnt.

what do I need to be able to use my production monitor rotated 90 degrees?

Re: Screen rotation

Look at this thread here: http://kubuntuforums.net/forums/index.php?topic=11533.0

May need to verify if you have "xrandr" installed and also there are some X11 extensions that need to be installed, I think when you install xrandr those will be included, but not sure. There are all installed on my machine, but I've never used that function.

Hope some of this helps.

Edit: This is from X.org --> http://www.thinkwiki.org/wiki/Xorg_RandR_1.2

Re: Screen rotation

had read that thread earlier, i did (locate xorg.conf) and got a few variations, which one do I add that line to.

I have xrandr installed (verified by man xrandr)

have now got the krandrtray icon but no facility to rotate, yet!

Which xorg.conf file (location) do I edit.

Thanks for the help

Edit: does it matter where I put that line of code in the xorg.conf file?

Re: Screen rotation

Remember, Always make a backup of any configuration file. That way if something goes awry, you'll have a means to go back.

Then Alt-F2 and type:

kdesu kate /etc/X11/xorg.conf

"xorg.conf" is the actual file X uses.

Re: Screen rotation

It goes in the "Screen" section.

Re: Screen rotation

ok we have rotation

however it leaves a blank piece below and chucks the right hand side off the screen, i have read that somewhere today, if you have a quick answer post it, i will be searching in the meantime.

My wide screen on the windoze pc is set at 900x1440 can the resolution be added directly to the xorg.conf file? is that what you must do?

Edit:

I found this on another forum

If all that you care about is getting the largest native mode, then remove all the modes, and just replace them with "nvidia-auto-select" and you should be all set

I take it it refers to this

		Modes		"1280x1024@60"	"1400x1050@60"	"1280x960@60"	
"1152x864@75"	"1024x768@43"	"1024x768@60"	"1024x768@70"	"1024x768@75"	
"1024x768@85"	"832x624@75"	"800x600@60"	"800x600@85"	"800x600@75"	
"800x600@72"	"800x600@56"	"640x480@85"	"640x480@75"	"640x480@72"	"640x480@60"

is this what I should end up with

I dont want to restart and have no screen available, please advise

		Modes		"nvidia-auto-select"

Re: Screen rotation

Yep, I'd be worried about that as well. I've never tried using screen rotation before, so past getting it setup, I would be in the same boat

Re: Screen rotation

what if i did this

		Modes		"900x1440@60"

would that be safe? don't want any headache

Re: Screen rotation

My best suggestion for this would be to wait for Hardy. The newer version of xorg included in Hardy will make this much easier. I recommend taking the live CD for a spin and see if it works.

Re: Screen rotation

thanks Mike but I want to get back to my production screen, I have only had Kubuntu installed for a week.

The figures in the xorg.conf file, how do they get used? why are there 2 categories under 2 headings like this (ive removed many numbers to keep it simple)

Modelname	"Custom 1"
 modeline "640x480@60" 25.2 640 656 752 800 480 490 492 525 -vsync -hsync
Gamma	1.0
EndSection

Section "Screen"
Identifier	"Default Screen"
Device		"nVidia Corporation G80 [GeForce 8600 GT]"
Monitor		"Generic Monitor"
Defaultdepth	24
SubSection "Display"
	Depth	24
	Virtual	1400	1050
Modes		"640x480@60"
	EndSubSection

what if I knew my screen size and wanted to hard code it, if it was hard coded like the sample above would that mean it would only display at that size?

I take it that there are many sizes available, are they determined by the monitor selected in the admin screen? are they selected to display the possabilities within the admin screen, do they populate the selection areas?

I'd actually try this. What I would do is see if it works and if it does, I'd look at the xorg.conf file the LiveCD generated. Worth a shot.

Re: Screen rotation

The xorg.conf from the live CD is going to be rather lacking since xorg 7.3 is moving away from the use of the xorg.conf file. It is actually possible to delete the xorg.conf alltogether is Hardy.

Re: Screen rotation

Thanks for that info, did not know that. Oh well, so much for that idea.

Re: Screen rotation

Screen rotation does work in hardy. I have only tried it in KDE4, it did not work real well there. KDE3 might have better luck?
