I too am seeing the issue where the screen stays black but the mouse cursor moves and changes shape normally. Eventually, after some long amount of time (which varies from seconds to minutes), the screen will suddenly restore as expected. I when it eventually restores it's usually coincident with a keystroke or mouse movement, but I don't have solid data. I am using a Radeon HD 7970 with 3 monitors, and Unity on Precise.
If I switch to VT2 , wait a little, and switch back, the problem persists. If I switch to VT2, log in, and kill the compiz process, and switch back, the screen restores as normal (except of course windows don't have decorations for a few seconds while compiz respawns, as expected). ** Tags added: precise -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/763422 Title: [i965] idle black screen plus other issues Ubuntu 11.04 Status in “xserver-xorg-video-intel” package in Ubuntu: Confirmed Bug description: Hello, I'm using Ubuntu 11.04. When I step away from the computer for a few minutes and then come back to it, usually I see the login screen that comes up each time you step away from the computer to get back to what I was doing on my computer, however occasionally when I come back and move the mouse the login screen is not visible and all I see is a complete black screen. The only thing I see is the white cursor, and only when I move the cursor over to the bar where I would enter my password would be, I get the insertion icon for entering text. But I still don't see the actual grey screen with the white bar to enter my password. I tried entering my password upon getting the insertion cursor when getting to the place where the white area would be to enter my password. I enter it, but all I still see is black. Obviously this is a bug, as I'm using a developmental version, 11.04, of Ubuntu, however I thought I should let the problem be known in the hopes and prayers that someone from the Ubuntu development team would see this post and fix the problem. And there is one other thing that I've noticed...the menu bar is all black at all times when I am logged into Ubuntu, except for the icons on the upper right hand side of the Ubuntu screen, such as the mail icon, wifi icon, etc. Those are slightly grey. The time however in that location is black however and basically unreadable. The only time I see the various drop downs from the menubar is when I hover over the menubar and click on where would be the various File, Edit so forth items on the menubar. Actually, as I'm writing this, for the first time I see the menubar items, File, Edit, etc., in black on a grey area in the menubar area, but they only appear when I hover over that area with the cursor, where they actually reside. I like the feature that the menubar itself, File, Edit, etc., only appears when you hover over it, but black text (menubar titles) on a very grey area isn't very readable. Lastly, occasionally when I rightclick with my mouse button to get a dropdown area in various areas of the screen, where it would be activated, such as to paste or cut text, it will appear for a second but then disappear almost immediately. Not long enough to actually click on what you want such as "Paste". I pray that the Ubuntu Team does in fact see this topic and implements the bug fixes soon, and in a way that once the OS is updated to represent these fixes, I can just update the Ubuntu Operating System through the Update Manager in the OS from within the OS I already have installed, and not have to reinstall Ubuntu all over again when the fixes come out. Thank you all so very much, in advance, for reading and appropriately responding to my lengthy post. May God Bless each and every one of you in The Mighty Name of The Lord Jesus Christ! He saved me and He can save you too if you are willing.
