Dual monitors strange behavior in 13.04 unselecting Mirror displays

Asked by James McLeod

Dual LG monitors strange (& functionalless) behavior in Ubuntu 13.04 when unselecting Setting/Display/Mirror displays. Everything except the current working panel of Settings is visible. Besides the menu panel selection disappearing, the panel & border of Settings vanish. This leaves me with no method of closing it... even Alt-F4 fails. I have no way to check anything.

CPU: 64AMD, Monitors: Two LG Flatron E2250T-PN (one through the HDMI port, other through the DVI port), Graphics Card: MSI R6670.

Works fine on Ubuntu version 3.5.0-17 in Generic Mode. Later versions, 3.5.0-25 & 3.5.0-26, have 'other' problems (not related to this question/query).

Booting from a DVD with Ubuntu 13.04 64bit, select the 'demo' mode, and everything looks good, except mirrored on the two monitors.

Maybe there's a work-around. But, I'm a programmer, damn it, not a systems administrator. (That was suppose to be humor.)

If needed, will the 'system' add a bug report, or must I do it?

- Jim

Does the system have a make and model?

What is the output of:

sudo lshw -C display; lsb_release -a; uname -a

Thanks

"sudo lshw -C display; lsb_release -a; uname -a" results in the following...

Seems you are using the open source driver. Have you tried the proprietary video driver?

Hi, I did and change to use the prop. driver fglrx+update and only the mirror mode was accept. I try to change to use others resolutions mode but, the system configuration was aborted with different kind of msg like "time out" or "the resolution exceed"; only once time when I used the fglrx only I can setup the resolution on 800x600

Can you help with this problem?
