cannot drag windows outside of 2048x2048 with virtual 2304x2048 on dual head

[geodni]

Hello,

First post here after years of reading, I didn't find any answers yet, so I give it a try here.

I can't drag any window outside of 2048x2048 resolution, I mean windows are well drawn outside this region until viewable virtual resolution fixed to 2304xx2048. Mouse can go alone outside 2048x2048. Mouse cursor just cannot go outside the 2048 horizontal value when I drag a window.

I am using FreeBSD 8.2 release -p2 on a PC like AMD quad/4GB of RAM with an addon Sapphire X1950 Pro 512MB, Xorg 7.5.1 and KDE 3.5.10_8. I have a dual head configuration rotated left (1152+1152)x2048 of Samsung Sync Master 2343 I manage with xrandr.

I don't know if it's an Xorg or KDE problem, I had it before the upgrade I describe above.

I have another problem but it can wait. It is since I made a buildworld/installworld and full upgrade of ports (portmaster, portupgrade and /usr/ports/UPDATING were my friends) coming from 8.0 release :
the first display only lights on after ~2 minutes when runing startx command and when running xrandr command, I must wait again ~3 minutes after playing with the second display font panel (switching on/off and VGA/DVI source) for it to light on.

I am starting Xorg with
startx -- :0 -dpi 75

After that, I just ran xrandr in a terminal with these options
xrandr --verbose --output DVI-0 --rotate left --pos 0x0 --output DVI-1 --right-of DVI-0 --rotate left

Here is my /etc/X11/xorg.conf configuration file

Any help, advice or comment wil be very appreciated. I can also provide more or missing information.

I hope I didn't run out of the Forum Rules in my first post.

Thanks,

That AEI should be removed, see AllowEmptyInput, FreeBSD, and Xorg Input (http://www.wonkity.com/~wblock/docs/html/aei.html). No idea what UseEvents might do.

The window dragging limits would likely be a function of the window manager.

Does it also happen when DRI is turned off?

If I'm not mistaken 2048x2048 is a hardware limitation.

It might be with some drivers or cards. I'm using 3200x1200 with radeon here. No problems, but not using rotation, and that's with xfce instead of KDE.

@wblock :

Because I don't use hald, I replaced AEI option like described in the link you provided with :
Option "AutoAddDevices" "off"
I removed UseEvents as it seems only used for nvidia drivers (http://magazine.redhat.com/2007/11/20/tips-and-tricks-why-does-xorgs-cpu-usage-shoot-up-when-using-nvidias-driver/).

@SirDice :

I just tested without DRI using Option "DRI" "Off" in Device Section with no success. Worse was obtained with Option "NoAccel" "True", no X environment displayed at all, I had to switch back to console using Alt+F1 and Ctrl+C startx command.

From official documentation (http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=298&pid=127&psn=0006&lid=1&leg=1) "Each display interface supports display resolutions beyond 2560x1600". I only use 2048x1152 rotated each.


I tried with newly created user (no ~/.kde* and more configuration files/directories), same behaviour happened.

I didn't tell you that font panel of my displays does not respond correctly when waiting xrandr command to rotate and arrange screen. Once desktop is well displayed, font panel responds normally to input switch or on/off.

Thanks.
