OpenSUSE Hardware :: Monitor Periodically Blanks Off And On?
May 24, 2010
I am running a nvidia gt220 video card and dual monitors. The acer monitor blanks out and in periodically. Quite often at times. I believe this is a driver problem. What I am wanting to do is roll back to an older driver. In the nvidia repository I only see the newest one listed and that is the one I am using.
I am thinking the 185 driver is what I have used before without any problems. Really not sure which one it was, but it was an older one. So the question is how can I get back to the older drivers so I can try and see which one it was.

After this morning's updates my Samsung SyncMaster 225BW monitor (1680x1050, 60 Hz) blanks every ten seconds. I've checked cables, even rebooted, logged into GNOME and Xfce and it continues.
edit: Oh, I'm running Debian testing.

It's a bit unnerving.The monitor suddenly goes black, the keyboard resets, the mouse resets. And after about 2 - 3 seconds all is back to normal.My USB setup is a bit complicated (mostly because I could). A 7 port hub is connected to a USB port on the computer. Among other things, the 7 port hub is connected to a four port hub on the monitor (Viewsonic). The mouse is connected to the 4 port hub. The PS1 keyboard is connected to the PS1-to-USB convertor which is connected to the 4 port hub.

I recently updated my girlfriends laptop (and my own) to KDE 4.4 (using the Factory repository). I am also using some additional repositories like PackMan.
I recently read on this forum, that the updater-applet is only updating from the main repositories (the ones set up after install). I would like to update from all updates periodically using "zypper dup".
I read somewhere else, that cronjobs are used to run scripts based on schedules. how I could run "zypper dup" with a cronjob and preferably under root, so I dont have to type the password every time?

On SUSE 11.2 when a CD or DVD is automounted (in the /media directory) it appears that the mount point chosen for the disk always has extra blanks at the end of the mount.
For example, if the label on the CD was DISK-001, the mount point chosen by SUSE is
/media/DISK-001 /
In 11.1 (and earlier) the mount point would have been
/media/DISK-001/
I'm assuming that the trailing blanks are filling in unused or blank chars at the end of the CD label.
Is there any way to change this annoying behavior? I much prefer NOT to have trailing blanks in the mount point.

This is a triple-monitor setup with two video cards, where the mouse pointer gets "stuck" if it tries to cross from one video card to the next one. It worked correctly in openSUSE 11.2 and doesn't work in openSUSE 11.3 with the same xorg.conf. This is a 64-bit openSUSE 11.3 with xorg 7.5-11.3 (the openSUSE prepackaged version). I've already tried NVidia drivers 256.53-16.1 (the openSUSE NVidia repository version) and 260.19.12 (the latest off of the NVidia website).
This is the same xorg.conf that I used successfully in openSUSE 11.2. I tried a new automatically generated xorg.conf using nvidia-settings and it had the same problem. This forum won't let me upload the relevant files, but here: [URL] is a tar-ball with my xorg.conf, Xorg.*.log, /var/log/messages, and the NVidia debugging output.

just setup suse 11.3 , put on the Nvidia 19.29-22.1 drivers via yast , no kms is set in inetd , nomodeset on grub boot line etc... Even tried installing the driver " the hard way " dual monitors come up, setup xinerama to "Extend" my desktop , and the main monitor ( right side ) is good, visually the left monitor (2ndary) is good.. but whenever I move my mouse over to the left screen the mouse pointer dissapears, flickers along the right hand border of that screen... and if i move the cursor back to the original screen i have to really fight to get it back to the main screen....Copy of my xorg.conf , still very basic...

Install went fine have Dual Boot Win7 and openSuse 11.3 KDE I have a 26" TFT TV as Monitor 1 DVI and Dell 16" as Monitor 2 VGA all working fine . Autoconfig started and TV display vanished, install finished and went into display settings to check problem and for some reason it is saying both displays are on my 16" Dell. I will Add Screen Shot to show problem. wanted to switch to Linux for years but never had the guts, i was hoping to learn Linux with this distro and when have a grip on it drop windows and use Linux as Primary.

We have a computer, was windows, we installed ubuntu. It worked well for several months, but once in a while the screen would blank out. The computer was still on, the lights on the computer box are still on, but I can't get the screen to show anything. In the last couple of days, it now does this a couple of times a day. I have to hit the computer off switch, do a shut down, and reboot.
Any particular set of keys I can switch to get the screen to go back on? Like ctrl alt delete?
Also, how do I check the computer to see if there are any problems with the computer? There is system, system testing, does that check the hard drive, start up sequence, anything else? What else can I use to test the computer, system.

Since upgrading to 11.04, my screen goes blank if I am not active for 10 mins. This is really annoying if I'm sat on the sofa watching a movie through the computer!
The screensaver is set to 1 hour and the power management settings are set to 'never'. I never had this problem with the previous Ubuntu version. I'm on a desktop rather than a laptop.

No problems with CD-RW, but DVD+RW are being blanked in an incorrect way. Ubuntu cannot recognize them at all after the blanking. I have to take the disks to another computer having Windows installed to blank them via Nero, and after that I they become OK for burning in Ubuntu via Brasero. I've got an old LG CD/DVD drive which was working fine in Windows. Who can recommend another program for CD/DVD burning for Ubuntu 10.04? (correctly blanking, certainly) I have installed the suggested updates for Brasero but of no avail.

I just connected my LCD TV to my desktop and now I get two things happening which I didn't get when I used a proper monitor:
the screen scrolls down and sort of flickers every minute or so, plus: every few minutes it goes competely 'blank' i.e. reverts to the blue screen of my TV when there is no signal.
It should be in Ubuntu NOT Kubuntu!

just my setup that causes this? (Ubuntu 10.04, Nautilus 2.30.1) MS file icons in Nautilus have a specific icon (e.g. a big X on green background for XLS), but OOo files have blanks.

When I start the Movie Player (Applications -> Sound and Video -> Movie Player), the screen blanks out and then restores again before playing the movie.
I don't see this issue with RhythmBox though. Only the Totem Movie Player seems to be experiencing this issue.

My debian squeeze + testing + unstable came with gdm3.
After setting in /etc/gdm3/daemon.conf:
AutomaticLoginEnable=true
AutomaticLogin=myname
I don't have to type in my username and password on startup. But after a few inactive minutes the screen blanks out, and I have to type in my password now in order to continue. For me hitting any key would be enough. How can I change that?

I'm using Debian Squeeze with Fluxbox and I'm having a problem with xscreensaver. I've set to blank screen after 10 minutos of inactivity, but the problem is that when I'm watching a movie, the screen is blanked after 10 minutes too. So I have to manually kill xscreensaver before starting to see a movie, or I have to move my mouse / press keyboard every 10 minutes to activate the screen again.
I've done some search before posting and I only found something about a SMPlayer's option named "Disable screensaver", but it is already on and it has no effect preventing xscreensaver to work. Here is a screen shoot of my SMPlayer configuration window:
[URL]
Apparently, xscreensaver isn't being able to recognize that another program is running. Could it be related to dbus?
PS: I had a dbus problem when I first upgraded to squeeze, my multimedia keys stoped working in banshee (whenever I clicked to play/pause/next etc, another banshee process was started), but I solved it by adding this line to my ~/.xinitrc: eval "$(dbus-launch --sh-syntax --exit-with-session)"

I installed 10.04 in a Dell Dimension 3000 for my father. It's a nice upgrade from the old Pentium 3, except for graphics it seems. I tried playing a video I recorded on my phone. Movie player(totem) appears to play the video, but instead shows a blank screen. Moving the window, minimizing, ect. shows a frame or two, but that's it. Converting to OGG, and turning off compix does nothing. I installed VLC and now the video plays but in slow motion. Sound works great in both. I'm not sure if it's an Intel graphics thing or what, but it's pretty bad when ..... plays better then local video.
BTW not sure if it's related but it also seems to have a problem coming out of suspend.

I'm running a fullscreen display app which shows a 3D scene in OpenGL. The app runs continiously throughout the day unattended.
Here's the sequence of events in how it's loaded:
1) The computer is turned on, and boots into F11 (x86_64)
2) A non-privileged user is automatically logged on
3) The gnome startup applications list contains an entry for a loading script
4) The loading script waits for the network interface (eth0) to ccome up, then starts the display program
This all works just fine, except that about 30 minutes after the computer is turned on and the app starts running, the screen blanks out. Attaching a mouse to the system and moving it around a bit brings the screen back to life. Likewise, SSHing into the machine and killing / restarting the application works as well. Once either of these fixes has been performed, it runs flawlessly for the rest of the day.
I have turned off the screen saver, and set the power settings for monitor shutdown to 'never'.

When I load the radeon module, from initscripts, the commandline, or when Xorg loads it, it makes all my consoles go blank. They are still active I can type into them then cat /dev/vcs* from X, and I see what I typed. I am using vga16fb as my framebuffer console driver, and am on PowerPC so I don't think I can use plain VGA consoles.
this is my /etc/modprobe.d/video.conf
Code:
install radeon /sbin/modprobe --ignore-install radeon modeset=1 tv=0
lspci | grep -i radeon
Code:
0000:04:00.0 VGA compatible controller: ATI Technologies Inc RV380 0x3e50 [Radeon X600]

I have Apache, MySql server, and phpMyAdmin installed on my desktop. With the default installation of phpMyAdmin, I should be able to log in as root without a password. (Or at least every other time I have installed it, I could.) However, that isn't the case. I can't log in to phpMyAdmin period. I have tried setting the password for root with MySql through the terminal. Still no results. No matter what I do, when I try to log in to phpMyAdmin, I am denied access.
this is a fairly common issue (though I have never encountered it before) as I found similar posts in numerous forums, etc. I finally found a solution and now have it working. In case others have a similar problem, I am posting the solution that I used here. First open a terminal. Then use the following command
Code:
mysqladmin -u root password NEWPASSWORD
Substitute NEWPASSWORD with the password that you want to use and then you should be able to log in to phpMyAdmin as root with the new password.

I have to run this page: [URL].., because it fetches the content of some feeds(RSS) and then inserts into Database and then sends SMS texts to subscribed users. when i run it with php-cli in bash like this: php feeds.php?u=y&d=y
I only get:
[4] 11719
but nothing happens, running it like this: black@loopserver:/var/www/loop/cp$ php 'feeds.php?u=y&d=y' Could not open input file: feeds.php?u=y&d=y
Can any one please tell me what to do? I think the problem is coming by passing get parameters, if i just run feeds.php everything goes fine, but I need to pass in those.

I want to use a script to renew my IP every 5 minutes. I have a static IP and it seems that when another person enter the same IP address as mine, my IP is stolen and is assigned to him.
I know that Cron is responsible for running a script at some time interval. How can I use that to renew my IP?

I just recently installed Xubuntu 10.04 on a new desktop and I have immediately begun to have issues. Within 10 minutes of installation, I had begun to look around to change the window 'theme' settings. I was scrolling through the themes and BOOM the system blanks out and forces me back to the login. At first I was thinking it was no big deal, but as it turns out, it will not let me back it.Basically, I use my credentials, it appears to login, it goes to a black screen with the cursor at the top left and then sends me back to login like nothing happened.

I have a custom .Xmodmap file to change the keyboard layout. The problem is that sometimes the keyboard layout changes back to the default. I have seen the lights on the keyboard blink at times, so I tried unplugging and reconnecting the keyboard and yes - that reset the layout. I can see keyboard removed/detected entries in the logs as well, so I guess my keyboard reconnects sometimes, I don't know why. However the solution from the post earlier (to rename the xmodmap file to ~/.Xmodmap) did not work. So is there another default filename I should use? Or do I have to enable xmodmap to run when a keyboard is plugged in somehow?
The only thing I can think of right now is to monitor /var/log/Xorg.0.log for "Adding input device USB Keyboard" and running xmodmap when that happens... but I'm really hoping for a better solution.If I can't fix the xmodmap problem, maybe I can fix the usb disconnects.I read something about power saving settings for usb. After some digging, I found that those settings are in /sys/bus/usb/devices/.../power/. However, disabling autosuspend for the hub did not seem to work (it was already disabled for the keyboard).
But I found something else in kern.log. Perhaps the keyboard disconnects has something to do with static electricity?
Code: Select all[ 7078.175830] usb 1-10-port3: disabled by hub (EMI?), re-enabling...
