[Ubuntu-x-swat] [Bug 529882] Re: black screen when switching between multiple X session
just adding that in case B sometimes the blank screen got back when cosing the switched user session. I solved it: 1. changing the above conf codes in xorg.conf from Option AGPMode 8 to Option AGPMode 1 2. completely removing the gnome-screensaver package as suggested here https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/546578 I don't know if these info are useful for debugging action.

[Ubuntu-x-swat] [Bug 529882] Re: black screen when switching between multiple X session
sorry .. the problem still remains .. so forget my previous posts :( It seems a problem of memory: if I switch without any app opened everything go right, but if just open some firefox wins and a openoffice document and then try to switch get the blank screen .. I tried to use the User Switcher panel applet, instead of the Indicator Applet Session as suggested here https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/546578 and that seems to work with all desktop effects turned off. However even in this case if I close all the user sessions through the User Switcher panel applet the gdm panel is no more shown and can only press ctrl+f1 login and write sudo /etc/init.d/gdm restart to get it. -- black screen when switching between multiple X session https://bugs.launchpad.net/bugs/529882 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

[Ubuntu-x-swat] [Bug 529882] Re: black screen when switching between multiple X session
Hello guys! Same problem here with a fresh installation of Lucid Lynx 10.04 final release: Motherboard - Intel D850GB (Garibaldi) cpu- Intel Pentium 4 - 2.0 GHz graphic card - ATI Radeon 9250 128 MB DDR problem: 1. logged in as admin user 2. try to switch to any user (admin or not with encrypted home or not) by pressing switch user under the menu of the right icon of the top panel next to the logged user-name 3. get a blank screen with no pointer. alt+f7 no effect, ctrl+alt+f7 no effect, ctrl+alt+f1/f2 etc sometimes got a console mode sometimes not. *** I found a work-around (don't know if this is the right place to post it): case A: you don't care about desktop effects 1. turn-off your desktop effects 2. reboot 3. it might be solved 4. if not type on a terminal: $ sudo chmod +w /boot/grub/grub.cfg $ gksudo gedit /boot/grub/grub.cfg find a line in your desired menuentry like: linux /boot/vmlinuz-2.6.32-21-generic root=UUID=95595d29-44d9-4b57-9b02-cbb5c5f127aa ro quiet splash and add nomodeset at the end to obtain something like linux /boot/vmlinuz-2.6.32-21-generic root=UUID=95595d29-44d9-4b57-9b02-cbb5c5f127aa ro quiet splash nomodeset $ sudo chmod -w /boot/grub/grub.cfg 5. reboot 6. it might be solved 7. if not I don't know :) case B: you do care about desktop effects This is more complex: 1. from a terminal install ati-drivers $ sudo apt-get install xorg-driver-fglrx 2. reboot 3. completely remove using synaptic any package with fglrx. In my case: fglrx fglrx-kernel-source xorg-driver-fglrx fglrx-amdcccle fglrx-modaliases (I know that I've installed xorg-driver-fglrx just now but I need some dependencies it install with the above command but I cnnot understand which ones .. so I first install it with all the dependencies and then I remove it .. ok?) 4. reinstall: libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-video-ati 5. reboot 6. it might be solved 7. if not (as in my case) type in a terminal: $ gksudo /etc/X11/xorg.conf and write inside the (blank) document: Section Device Identifier Configured Video Device Driver ati BusID PCI:1:0:0 Option XAANoOffscreenPixmaps Option AGPMode 8 Option AccelMethod EXA Option ColorTiling on EndSection save and close. 8. turn-on your desktop effects and try to switch user and it might be ok. Sometimes when closing the session I get a prompt asking me to enter the password rather then getting the gdm gui .. on this prompt I cannot click on the bottom buttons (something as change user leave a message and so on ) but I can still reach them by using the alt button.
