I usually use my Mac in fullscreen X mode, and had delayed switching to Leopard because it didn't work. Seeing that it's now available, I have made the switch and installed 2.3.2_rc1. I'm using fvwm2 as my window manager. Here are some problems I've encountered. Some of the things I mention below should probably be submitted as bugs, but as I haven't been through the bug list carefully yet I thought I'd raise them here first. (1) White rectangles. I see there is already a bug report for these, but I'll describe what I get anyway. There appears to be a white rectangle for each pop-up window, mostly menus. They don't appear immediately after popping up the menu, but after switching to the main Mac display (alt-apple-a) and back to the fullscreen X display. They don't obscure X windows, just the background. But if I switch to the Mac display again, they are there too and *do* obscure other windows. Popping up the same menu again makes them go away until I switch to the Mac display again. (2) Sometimes on starting up X in fullscreen mode the menu bar appears at the top - and in one case something appeared at the bottom - and goes away when I move the mouse over it (or perhaps when I click - it hasn't happened often enough to be sure). I don't have "auto-show menu bar" selected. (3) On one occasion, on starting up X I got the X background with a beachball cursor. The only way I found to get out of it was to log in from another machine and kill X11.app. alt-apple-a did not work. (4) On one occasion after switching to the X display the cursor was stuck in the top-left corner. Switching to the Mac display and back fixed it. (5) My xterms (started with "xterm -ls" from fvwm) have / as their current directory. I guess this is because that's the window manager's current directory. (It occurs to me I can probably fix that by putting cd $HOME in my .xinitrc, but I haven't tried it yet.) (6) The window manager and initial xterm appear to have their DISPLAY variable set to /tmp/launchd-xxx/:0, but xterms started later from fvwm get :1.0. Why is there this difference, and why is it :1.0 instead of :0.0? (This is inconvenient because I have code that assumes - perhaps wrongly - that if DISPLAY is something:n, then hostname:n will work from another machine.) Despite these problems I'm pleased to have fullscreen working on Leopard, and I'd like to thank all those who have worked on it. -- Richard -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.
