 Appear to grow the screen real estate quite dramatically, as judged by
 a portrait image I use for background, growing quite noticeably and
 the panel KDE had at the bottom of my viewing area is moved down out
 of site.

 Apps that happen to be running are shifted to the right several inches
 it appears.

 But the mouse cannot pan out into the larger size.  It appears to
 still honor the original screen borders.

 It may be another manifestation of the mouse boundary aka border
 patch. While I don't know if the bug is (still?) present in X.Org
 sources, e.g. Fedora 15 ships the X server 1.10.4 with the (buggy)
 patch added.

 A year old Fedora bug report is here:
 https://bugzilla.redhat.com/show_bug.cgi?id=655212

May I ask if you personally use a large panning desktop?

Thanks for your input.  It appears this bug has not gained much
attention but for your information; An announcement was recently
posted on an Xorg list and I asked that developer about this problem. 

His response was somewhat encouraging... if you are interested see the
thread on `gmane.comp.freedesktop.xorg' beginning with this subject and
msg-id. 

 Subject: xorg-server 1.11.1.901 (1.11.2R C1)
 Message-ID: 70678e1b-dc37-4a6a-8b35-712a0b10f...@freedesktop.org

I do, using nouveau (there were driver bugs in such config, I had to use
vertical X Y equal to xrandr X Y), radeons (work fine except the
cursor sometimes behaves interestingly near the physical border) and
intels (probably same cursor oddities?).

I also use a dual-screen setup where for example the bigger screen is
1920x1080 and the smaller laptop screen uses panning (with cloning - the
border patch doesn't matter in this case).

Not counting the need to revert the Fedora border patch and the cursor
issues, it works flawlessly.
I also use it, from time to time, with chips like Silicon Motion
SM722(?) and with Volari Z9s.

I don't know if my desktops are large though :-)

Re: XPutImage stops returning to caller

 The calling parameters do not change, nor indeed the pixels being passed

 Any ideas what might be happening? (For what it is worth, the

 Any help with getting my application to link to libX11-6-dbg would also

x11perf also supports XPutImage (see man page). Perhaps you can try
to replicate that effect.

Re: multiseat on lap top

2011-10-15 Thread stompdagg...@yahoo.com
kdmrc doesn't cares about xephyr.

it depends on the xorg.conf.

I don't use xephyr but I imagine that it creates a virtual card which in turn 
is used the same way one configures multiseat with more then one cards.

external gpu might be ugly, but you'll gain better performance.

Thanx
I am aware of the necessity of hub for in and mouse.
The only thing I have to overcome is setting a conf besides  kdmrc or xephyre 
to use a single graphic card with two output port for monitors which almost 
always laptops are equipped with this kind of cards.
So I need settings for such cards. As I know the chest and xephyre are the most 
common xservers which work on top of another xserver. As they are capable of 
using a graphic card as many as output port of a card, the solution rest on 
using one of those programme. 
Once I read a threat on a famous developer site from a brithis guy on the 
subject. But he refused to give me the settings he had.
As it is a painful job I did not dear to start it.
It is why I am asking for help.
An external graphic card is a solution but is a little ugly. Having a hardware 
beside a laptop does not sound nice.

in general, for each seat you need at least 2 usb/ps2 ports and 1 display port.

for 3 seats you need 3 display ports and 6 usb inputs, in all of the laptops 
I've seen, there was a max of 2 display ports and 4 usb ports or 2 usb and 2 
ps2 ports.
the only way you can have a 3 seats multi seat conf on a laptop is either 
using the actual comp as a seat or getting hubs for the usb and external gpu.

imho either two options might impact the performance as multi seat tends to be 
heavy and laptops usually aren't that powerful.

as I'm not using fedora, I cannot comment on the possibility of doing that on 
fedora but I'm sure you can find useful info in fedora's docs.

btw, the old man is god, but we leave it be.

Thanks to you and the old man (as Einstein called man's created God)
I have read setting up multiseat using one single graphic card is possible 
through xephyre. Assuming laptops have two or three monitor out puts, is it 
yet possible to have multiseat on laptop.
I am not prophi. But I could make a multiseat on fedora14 with an internal and 
external graphic card setting kdmrc and sort.conf.

you can try and see if getting an external gpu is worthwhile.

has anybody some experience on usage of multiseat on laptop?
should I use Xephyre inevitably?
