Re: XP black screen on initial connection
There really haven't been a whole lot of suggestions on this issue. No FIX yet, just work arounds. If you disable user switching, I think it will work (you won't be able to log in simultaniously).

I prefer to use Remote desktop for some things and VNC for some things. I do NOT need both at the same time though. By chance, do you know if and how I can do that?

Re: XP black screen on initial connection
Only one user is running on the real video card...the other user works in a internal RDP "Terminal session" Vnc can not capture Terminal sessions.. There is no work around. Something seems fishy here. I'm sure that on the local machine, if you switch a user, it may use a "virtual" session for the other users, but that really has nothing to do with what you should see when you do a vnc session. VNC should grab whatever the video card is streaming to the monitor, regardless what other sessions are going on behind the scenes. I'm going to fiddle with it a bit more when I get home, I'm going to take a look at the code and see if I can figure out how it gets it's session/stream. What kind of revisions are happening with VNC gold? Is it going to handle this differently or something?

Fast user switching ??? Only one user is running on the real video card...the other user works in a internal RDP "Terminal session" Vnc can not capture Terminal sessions.. There is no work around.

In fact, I have many times attempted to replace my Windows environment with many of the available Linux distributions, as well as BeOS, but I always find myself reverting back to Win2K/XP. As far as RD goes, I am convinced that /something/ happens with the display driver during the session, -- exactly what that /something/ is, perhaps no one (besides M$) will ever know. Perhaps everything will all pan out with Windows XP SP2 and with RealVNC 4.0 Gold. -Adam ___ VNC-List mailing list [EMAIL PROTECTED] To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list
Re: XP black screen on initial connection
Thanks, Adam, for some good insight on what you think the problem is. I'm having a hard time believing something can't be done about it on the VNC side though. Fixes, to me, don't mean "don't use it", they mean "change this and it will work", so I'd like to pursue this a bit further. While a remote user is in a remote desktop session, the local computer screen is at the "welcome screen". The resolution hasn't changed and the user can log in and interrupt the remote desktop session if he chooses. The local screen is still there, and usable, so I see no reason VNC should not be. MS will continue to have support for Remote desktop as a way to phase out VNC and push their proprietary version. I prefer an open source version, rather than a microsoft version, maybe we can figure this out if someone has some insight on the subject.

I don't know of any VNC-specific fixes regarding this issue. However, there /is/ a Windows XP-specific fix: 1) *DO NOT* use the 'Welcome Screen' 2) *DO NOT* use 'Fast User Switching' 3) *DO NOT* use 'Remote Desktop' (I am not sure if 1 and 2 are completely necessary) So, in essence, all I can recommend is to forget about using Remote Desktop, or to forget about using VNC -- they currently can't coexist. Maybe this issue will be resolved by the time version 4 has gone gold. It seems to me that the reason this happens is because the Remote Desktop session changes the screen geometry, but doesn't revert it back to the normal user's resolution until *after* they log back in; so when the RD session is finished, the geometry is in limbo mode. It has been my experience that after the normal user continues his/her interactive session, VNC will connect without any problems. -Adam ___ VNC-List mailing list [EMAIL PROTECTED] To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list

Re: XP black screen on initial connection
I just got an email from someone regarding this same issue, it reads: Hi - I have been searching for an answer to the same problem you have had with using VNC after using MS Remote Desktop. Do you have any information on this issue please ? Thanks, Ron Coleman I know this is a known issue, can anyone enlighten us and the many more out there with the same bug?
