XDMCP login using compiz cause reverse menu and graphics on client

[Christos Choutouridis]

I have configure XDMCP logins on a Desktop machine running Ubuntu 8.10 and compiz-fusion. I did it via the gdm menu "System->Administration->Login window"
If i try to remote login via XDMCP from a client, running Ubuntu 8.10 and compiz also, i can login successfully but the graphics are false.

->The desktop is reversed and the desktop icons are in the bottom of the screen and up side down also.
->The menus are in the right places but totally reversed. The name of one program is in the place of an other and the fonts are mirrored.
->If a window appears, the graphics and the buttons are in the wrong positions and the fonts are mirrored also.
->The mouse seem to be the only think that works.

The same issue appears when i try to login on a debian machine (Lenny running compiz). But. If i chose not to run compiz on the client everything is fine. The problem seems to appear only if the remote machine tries to enable compiz

I can confirm this issue in 3 PCs as XDMCP servers, running ubuntu 8.10 and debian Lenny. And in 7 PCs as clients running ubuntu 8.10

These changes caused by farther search on this issue.

I am also seeing this issue.
My setup is a Dell 4500 with Ubuntu 8.10 fresh desktop install, all updates as of 2/272009 for standard install.

I am trying to remote login using a Lenovo S10 netbook, also base desktop 8.10 install, all updates as of 2/27/2009.
Please let me know if I can be of assistance or if additional system information is needed to help diagnose.

Same issue here.
Ubuntu 8.10 for the client, Debian testing for the server.
I searched some workaround with ccsm but no result.

[James Landritsi (xlandisx)]

Is there any development on this issue?

[Oleksij Rempel (olerem)]

Disable compiz is the workaround. And here is screen shot, looks nice ;)

This bug still exists in 9.04. I wonder why nobody is working on it as it is really annoying...

[ledzepjes (ledzepjes)]

I am still getting everything upside down also, this is VERY annoying. I know of a lifehacker issue that desribed how to mess with someone's internet connection if they are stealing your wireless internet, make a connection available to the outside world that is unencrypted and make all the pictures load upside down on the client computer, mean but not as mean as stealing internet, haha, it's very much the same thing going on with xdmcp: http://lifehacker.com/190441/turn-your-wifi-piggybackers-internet-upside-down

I too get this in 9.04. Very annoying since my other computer doesn't have a monitor.

Hi all,
got the same problem here,
when i do : compiz --replace

all become just like inverted as in a mirror,
I can provide information, ask if needed.

My gpu is :
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GME Express Integrated Graphics Controller (rev 03)
00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03)

I use compiz-fusion package from the repo,
I don't think it come from set up of compiz because I reinstall, and all desactivate in ccsm but it still apening.

I'm new here, feel free to link to see to help a bit,
In advance many thank's.

:)

Have the same problem with Ubuntu LTSP Server. My GPU is GF8100 IGP.
Low importance and nobody assigned looks lamentably.

So we call glXGetFBConfigAttrib (display, fbConfigs[j], GLX_Y_INVERTED_EXT, &value); to see if we should flip the y axis when drawing or not, apparently due to the different hardware in the host vs the client this is not working correctly. I can't see of a way around this though, except for each of you modifying the source to change yInverted to whatever value is needed for your situation.

I'm pretty sure the X call in this case happens on the host which
gives wrong values for client-side rendering. In any case, there's not
much usecase for this - we should look into reviving the nomad patches
and promoting RDP as the way to do composited sessions
