When I leave vncviewer or Remote Desktop (using vnc protocol) opened for a long time (more than 10 min) - mouse pointer disappear. I'm using fc3 on IBM R50 laptop with USB mouse and TrackPoint. When pointer disappear I can not use not USB mouse nor TrackPoint, but if I switch to another text console I got my mouse back.
I can reproduce this bug at will: I use vnc on my linux workstation to connect by vnc to a windows computer running UltraVNC server. I don't know if the server is important, since the bug exhibits itself at both places. One detail that IS important is that vncviewer must be running FULLSCREEN, otherwise the bug will NOT manifest itself. At that point, if I leave both computers idle until both their screen-savers come on, the bug happens. If I then move the mouse or touch the keyboard (makes no difference which I pick), the mouse pointer will seem to have disappeared on BOTH computers. The only way I've found in which you can extricate yourself from this is by using the following method: I press CTRL+ESC, causing the Windows START button to act as if it had been clicked with the mouse. This has the side-effect of setting focus to the START button, I then press tab until the focus-rectangle enters the system-tray, I tab to the VNC server's tray-icon, press SHIFT+F10, and from the pop-up menu that appears, I use the arrow-keys to select "Kill All Clients" This drops me back onto my Linux workstation's desktop. UNFORTUNATELY, there is still NO MOUSE POINTER. The trick now is to let xscreensaver come on. The moment the screen-saver comes on, I move the mouse and VOILA - Everything is back to normal. No bug. So there is an interaction between X11, VNC (client) and xscreensaver. The reason I think X11 is involved is because I have never seen this bug when the roles are reversed (Windows as the workstation running the VNC client)
I confirm this behavior on FC4. Here is the version info: VNC Viewer Free Edition 4.1.1 for X - built Aug 4 2005 06:43:41 However, I do not get the mouse back when going to console. I have to 'killall vncviewer' in the console and then return to X, wait for the screensaver to kick in and only then the mouse returns. I suspect that the problem is related with the screensaver.
I confirm this issue on the following configurations: - FC2 with Xorg 2D accelerated drivers - FC3 with Nvidia 3D accelerated drivers - FC4 with ATI 3D accelerated drivers Conditions: not only connected to a VNC server, but also to an RDP one (MS Windows Remote Display Protocol) using rdesktop. I am using the "blank" screen-saving of xscreensaver. The proposed work-around (killall rdesktop & wait for anoth resume from screensaver) does not work for me. I always have to kill (Ctrl+Backspace) the X server & restart my whole environment (*extremelly* annoying).
Sorry about the phenomenal bug spam, guys. Adding xorg-team@ to the QA contact so bugs don't get lost in future.
