[Bug 71030] Re: Lock Screen blanks screen instead of showing screensaver (on external monitor)
I have a similar issue where sometimes when I come back to my W510 thinkpad laptop (nouveau drivers, U10.10) I see a black screen with a mouse icon. There is no screen-saver lockout screen. System is functional but cannot use screen. This happens about once a week and is very annoying. Let me know if there is any log I can capture. I noticed Xorg is at 100% CPU when this happens. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/71030 Title: Lock Screen blanks screen instead of showing screensaver (on external monitor) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 71030] Re: Lock Screen blanks screen instead of showing screensaver (on external monitor)
hey SkullBurner, I'm having the exact same problem! I have Ubuntu 10.04 64-bit on an Alienware m15x laptop with Nvidia GeForce 8800M GTX and in nvidia- settings I have my laptop display disabled and use only my external. When I have my laptop lid closed I only get a blank screen for my screensaver where when the laptop lid is open I get the screensaver. Same thing with put the display to sleep function; it works when laptop lid is open, but once it's closed my external will just stay on a blank screen forever, I have to shut off the screen when I go away for a while. I've posted this problem on the ubuntu forums and haven't heard back. It's a really annoying problem. I think it might have something to do with the fact that I'm using nvidia settings to configure the displays. Maybe gnome can't detect the nvidia settings I've made and it just sees the my laptop screen is disabled and thinks I don't have an external??? Could you post what kind of graphics card you have, what you use to configure the displays. -- Lock Screen blanks screen instead of showing screensaver (on external monitor) https://bugs.launchpad.net/bugs/71030 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 71030] Re: Lock Screen blanks screen instead of showing screensaver (on external monitor)
Hi, I have noticed following behavior regarding gnome-screensaver and gnome-power-manager on my laptop. If I switch from internal display to external one and then close the lid of the laptop then screensaver only shows blank screen instead of selected theme. If I open the lid while screensaver is still on then the selected screensaver theme is activated and stays on after I close the lid. If I stop the screensaver by moving mouse and let it start again while lid is closed only blank screen is activated. Also Gnome-Power-manager doesn't switch off external display after the idle time set in the parameters, the external display stays always on if I close the lid of the laptop or/and I switch off internal display. There must be some logic in gnome-screensaver and gnome-power-manager that looks if laptop internal screen is off or if the lid is closed and then it does not activate screensaver or DPMS features because they are not needed. Problem is that if one uses external display with internal laptop display swithced off or lid closed screensaver should be activated and DPMS should still work for external display. I think gnome-screenasver and gnome-power-manager code should be changed to become aware of the display that is being used and if the external display is used they should ignore on/off status of internal display or lid position. I have noticed that if I switch the internal display to external display while my laptop lid is closed and after external display is activated then I kill gnome-screensaver and start it again then screensaver is working properly on external display despite the fact that laptop lid is closed. I have tried same procedure with gnome-power-manager but it doesn't help with it.

[Bug 71030] Re: Lock Screen blanks screen instead of showing screensaver (on external monitor)
I'm having the same problem, using one nVidia card with two monitors (laptop monitor + external LCD screen connected through d-sub contact), running Ubuntu 7.10. It has always worked before, but today, the laptop screen goes black after gnome-screensaver starts, and stays black. I can only see the mouse cursor. The other monitor works fine.

To add some more detail. I can change the two devices in my xorg file from 'nvidia' to 'nv' and the problem goes away (with everything else in the xorg exactly the same).

[Bug 71030] Re: Lock Screen blanks screen instead of showing screensaver (on external monitor)
Confirmed on Feisty running gnome-screensaver 2.17.4 with two nvidia cards and three monitors running Xinerama. This is when using the nvidia binary driver. (I did not have this problem with the nv driver.) When gnome-screensaver is activated (either through inactivity or via ctrl-alt-l), the primary monitor fades out for a second, and then blanks. At this point, gnome-screensaver has crashed with the following error message: gnome-screensaver-Message: Found best visual for GL: 0x21 The program 'gnome-screensaver' received an X Window System error. This probably reflects a bug in the program. The error was 'BadColor (invalid Colormap parameter)'. (Details: serial 246 error_code 12 request_code 1 minor_code 0) I can attempt to get a backtrace if someone can point me to the -dbgsym package for this version of gnome-screensaver. ** Attachment added: xorg.conf http://librarian.launchpad.net/5666044/xorg.conf -- Lock Screen blanks screen instead of showing screensaver (on external monitor) https://launchpad.net/bugs/71030 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 71030] Re: Lock Screen blanks screen instead of showing screensaver (on external monitor)
A few other observations, gnome-screensaver only blanks the primary monitor - the other two monitors are not blanked and continue to function normally. Even though the primary monitor is blanked, I can still see the mouse cursor when it moves across that monitor. I don't know if it is related, but I am also unable to run gnome- screensaver-preferences. A window flashes on the screen, but then the program exits with the following error message: e# gnome-screensaver-preferences (gnome-screensaver:7708): GnomeUI-WARNING **: While connecting to session manager: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed. gnome-screensaver-Message: Found best visual for GL: 0x21 The program 'gnome-screensaver' received an X Window System error. This probably reflects a bug in the program. The error was 'BadColor (invalid Colormap parameter)'. (Details: serial 232 error_code 12 request_code 1 minor_code 0) Note that the error text is the same as in the gnome-screensaver error, but the serial number is different. -- Lock Screen blanks screen instead of showing screensaver (on external monitor) https://launchpad.net/bugs/71030 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 71030] Re: Lock Screen blanks screen instead of showing screensaver (on external monitor)
Here's a workaround: I restarted X, then killed gnome-screensaver. At this point I could start gnome-screensaver-preferences, and so switched from 'Random' screensaver to 'Blank Screen'. From this point, ctrl-alt-l started the screensaver, and it worked on all three monitors, and went to the unlock dialog properly on activity. Looking through the various screensaver options, it appears a handful of the screensavers work (apparently the non-3D ones?) I did see the following error messages when the screensaver activated, but haven't seen any other misbehavior otherwise: (/usr/lib/gnome-screensaver/gnome-screensaver-gl-helper:9778): Gdk- CRITICAL **: gdk_x11_visual_get_xvisual: assertion `visual != NULL' failed (/usr/lib/gnome-screensaver/gnome-screensaver-gl-helper:9779): Gdk- CRITICAL **: gdk_x11_visual_get_xvisual: assertion `visual != NULL' failed (/usr/lib/gnome-screensaver/gnome-screensaver-gl-helper:9780): Gdk- CRITICAL **: gdk_x11_visual_get_xvisual: assertion `visual != NULL' failed A few thoughts on fixes for this bug... 1. Add a new Random2D screensaver theme which activates only the non-3D screensavers. 2. Or add a mechanism to detect if the user's X config can actually run the 3D screensavers and only enable them if the prerequisites are met. 3. Since gnome-screensaver-preferences was crashing, I couldn't turn off the screensaver that was causing the problem. Perhaps include a checkbox for being able to see previews of the screensaver, that's off initially by default or something. -- Lock Screen blanks screen instead of showing screensaver (on external monitor) https://launchpad.net/bugs/71030 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
