Ubuntu :: Installed The Upgrade Lucid And Display Does Not Turn Off?
May 4, 2010
I just did the upgrade and I want to turn off the display after 30 minutes. I check that selection but the display does not turn off after 30 minutes. It is still on. I enabled this setting through the power management. The screen saver is on, go to blank display but the monitor does not turn off.
On Windows, dual boot on the same machine, the monitor does display off. I don't know if this is part of the problem or not, but when I go to "System -> Preferences", there are two different "Screensaver" options.

I had ubuntu 9.10, and every time i turned on my computer it would prompt me to upgrade, so finally i did. I let it upgrade over last night, then finished it this morning. when it went to restart, it turned off fine, but when it came back on, the screen goes through the Gateway first thing where it shows like F10 for boot from etc, and then the screen goes to a black command line looking screen, then it says ubuntu for a second, and then the screen goes black and does nothing. i let it sit for about an hour to see if it was just running slow, but it was still black when i checked it, so now my laptop is useless until i figure something out.

I upgraded to Lucid last night, and I'm getting this error when I try to run virtualbox-ose:
Quote:
Kernel driver not installed (rc=-190 Please install the virtualbox-ose-dkms package and execute 'modprobe vboxdrv' as root.
I try it, then I get:
Quote:
modprobe vboxdrv
FATAL: Module vboxdrv not found.
I have no idea what's going on. Can anyone help? The version of virtualbox is 3.1.6-dfsg-2ubuntu2

I am running a service (Selenium) that relies on launching browsers, even when there is not an active display. So in my startup script, I have
Code:
What is the equivalent code I should put in the shutdown method? In other words, to de-activate the display? Right now, if I restart, I get the errors ...
Code:
server:
Fatal server error:
Server is already active for display 15 If this server is no longer running, remove /tmp/.X15-lock and start again.

I have XFX ATI-HD5670 and use proprietary catalyst 11.2-1 in 64-bit Fedora 14.
I am not sure when this started, or if it ever did work before, but when I started noticing that the screensaver will not turn off the monitor, I set the gnome power manager to make the monitor sleep after an hour.
Now, the display will not turn back on after it has been in sleep mode. I know the system is still running fine as I can ssh from another PC and see that everything seems to be normal, no error message in dmesg, /var/log/Xorg.0.log, etc.
/var/log/Xorg.0.log shows that monitor DPMS is not detected but still enables DPMS:
Is this a problem with catalyst driver? I know it's not the PC or the monitor, because I have a 2nd PC with the same video driver with the same problem, but others without this driver don't (ati open source, nvidia, etc. all work fine.)
I'm wondering if the problem always existed before, but I just didn't notice it because the display sleep mode was never set? If that's the case, my hunch is that it looked like it worked because the monitor was smart enough to turn itself off when the screensaver kicked in and just showed a blank screen, and the video driver was never involved with sleep mode until I set it in gnome power manager, at which point it started showing this problem of not waking up? And because the screensaver was no longer set to blank the screen, but to show some animation, that's why the monitor will never sleep anymore?

I frequently watch movies on my computer, but I have two screens. So having something displayed on the other monitor is annoying.
I currently use this to turn off my monitors:
xset dpms force off
I was wondering if there's any way to turn off monitors independently, without having to physically press a button on the monitor, of course.
A program that tells the other monitor to display nothing but black would suffice, but I'd really prefer not to waste the power.
I also have Nvidia TwinView, so applications like grandr aren't aware of both monitors as being independent.

I've got a rather annoying problem with OpenSUSE 11.1 x86_64, I can't turn off the display power management! I've tried from the KDE 3 and 4 settings as well as GNOME, and finally YaST2. There's nothing in monitor's controls (the buttons on the monitor itself). The actual GUI controls in KDE/GNOME/YaST2 work (as opposed to being grayed out or disabled) and the system doesn't complain when I hit apply/OK, but every time I disable display power management, I wait about 15 minutes and sure enough, the screen blanks. I've checked and made sure the screen saver is disabled, I've looked for a setting to change in the YaST2 sysconfig editor and the kernel settings app, but can't seem to find anything. The only other thing I can think of is to try the acpi=off kernel boot option. I'd rather not resort to that. Anyone know if there is some super secret hidden setting somewhere that might be overriding everything else? Could this be some sort of ACPI incompatibility issue?

Everything look great but I don't get how to connect to ethernet connection or how to turn on wireless. I always had automatic connection on ubuntu since 8.04. For now I'll look for some repository and download the "nt" applet manager.

I just installed 10.04 Lucid Lynx and have a serious graphics problem. I've attached a picture to show the problem.
Some Background:
Pentium 4 3.06GHz
1.5GB RAM
ATI Radeon 9600
I installed via liveUSB but had to choose the "nomodeset" option by pressing F6. Otherwise after the Ubuntu boot screen the graphics went like that in the attached image. The installation went fine (took less than 15 minutes!) but after the reboot the graphics problem returned. I can't see anything and the system is useless this way. I can't post up any logs (I'm typing this from the liveUSB).

When I booted my computer this morning (lucid lynx 10.04, 2.6.32-21) I found that it showed me a login box, much like normal, but that the text field where I type my username was about a pixel high and disabled. So I couldn't type my username, or password, and had to resort to a tty and links to get here and ask someone for help. I can't find anything on google that looks like people having the same issue and frankly I'm not even sure what is wrong.

For some reason I am unable to get Thunderbird 3.0.4 to display html in a message. I can see the html code when I chose to "view source", but the message itself is totally blank. I am using Ubuntu Lucid.

I recently updated to Ubuntu Lucid Lynx from Karmic (fresh install though). All of the packages I used in Karmic seem to work nicely in Lucid, with one exception gnome-rdp. I'm a sysadmin in several windows environments so as you can imagine I love the session storage and grouping features. Unfortunately gnome-rdp is not displaying the group names. it stores my session and creates the group structure just fine, it just doesn't show me the group names in the app or the right-click menu on the top panel icon. My gut says it has something to do with the new Lucid theme, but I like the new theme. Does anyone know of a config file I can edit, or something I can do to disable theme integration, just for gnome-rdp?

I have a lucid stock install of Ubuntu, and the visual effects are set to Normal.
The Windows-E shortcut brings up the 'expo' display of all four workspaces in a line.
Is there a way of making (say) the top right corner of the screen sensitive so that moving the mouse there triggers the display of all workspaces?
Can this be done with 'stock' installed software?
gconf-editor has a promising looking key called 'expo_edge' at
/apps/compiz/plugins/expo/allscreens/options/expo_edge
but that might do something different.

I'm having trouble displaying Xwindows programs on a remote machine. If I run "ssh -X newmachine" and I login and then run a program like xclock, I get the error message:
Error: Can't open display: localhost:10.0
If I run the same command to an anothermachine which is running Ubuntu 8.04 it works fine and xclock displays on my localmachine. If I run the command "echo $DISPLAY" on newmachine, I see:
localhost:10.0
Also, I have checked and xauth is installed on newmachine. What setting I have to change on Ubuntu 10.04 to allow remote display of Xwindows programs?

My daughter from New Zealand gave me her Acer Aspire 4315 Laptop/Notebook Linux System in December 2009 so that I could use it in bed on days that I was unable to get out to use my main computer as I am a very ill man. I was able to log into the unit as she just said to me to use her name and password to. I have been able to use the unit on the internet at home and my other daughters home through a home wireless system. I clicked on the Upgrade Icon which it did, I think it went from a 7. something to 8.something All the way through the set up it asked me questions and I just clicked yes thinking that was what I had to do. My problem now is, that when I turn the unit on it asks me for a username and password. I put the details my daughter gave me but it tells me invalid user and password. All I do know is that a friend of my daughter installed the Ubuntu Program onto the Laptop/Notebook. Can anyone tell me how or what I have to do now to be able to use the unit again as I am getting very frustrated with the whole thing. I am not used to using Ubuntu and am totally lost with it as I have always been a Microsoft user.

Lucid installed without any errors that I can see of off the main i386 installation CD, but after booting I get no display. Even in recovery mode. The monitor doesn't go into sleep mode and I can tell that the OS is actually running the background because I can do a Ctrl-Alt-Del and do a proper shutdown. I'm running an nvidia GT 9500. Everything is working fine on Karmic.

Laptop only has external display. When karmic boots 2.6.31-21 and initrd.img has finished loading, and I have taken quiet splash out of boot line, I get nothing on the external display until gnome come up. Does the kernel driver only recognise internal displays until X takes over, or is there something wrong with the karmic 855GM kernel driver?

I have Lucid 64 connected to my 27" TV with 4:3 aspect ratio via s-video from an nVidia NV4 GeForce 6200SE TurboCache 256 MB card using the 173 driver set at 800X600. After hours (don't get on my case, this is the first time I've had hardware that would run well on a TV) and hours of tinkering I've gotten a feel for how to do this and have some pretty good results. However, I have two problems.
.01 The display isn't quite filling the entire screen. It's leaving about a .25 inch black bar all the way around the screen. This is negligible and if I can't fix it with only minor adjustments then so be it. I can live with it.
.02 This one isn't so minor. Many of the Windows are opening with portions of themselves cut off of, usually, the bottom of the screen. This makes, among other things, getting to the Close button rather impossible.

Running fine for a couple of weeks now, my Ubuntu Lucid install on a Sony laptop Vaio VGN-N21E went through some updates an hour ago. After the updates were installed, I shut the laptop down. The shutdown was slow but graceful with no errors. Now, when I try and power back on, I get errors about CIFS stating that the network share I map to could not connect. Also, that the network could not connect. I usually connect wirelessly and had no problems until now. It lets me log in but freezes after I see my desktop. No cursor or keyboard response...no response to CTRL+ALT+DEL...I can only manually force shutdown....

I am running usb version of lucid 10.04.2, with many apt-get installs. Shortly after running awhile, programs will not run, I get either an "input/output error" or "Bus error (core dumped)". (Examples of programs rendered inoperable are top, df, file)
I've read something about a memory leak in Lucid, but in my case, the computer doesnt slow down, things just stop working. Is this a known problem with Lucid? I'm thinking maybe one of my apt-get installs corrupted something. Is this a known problem that has a software update available?
Here is the output of "top" which fortunately currently DOES work, while other progs don't. (the memory usage stays constantly in that 1.5 GB range)
Mem: 3056772k total, 1554952k used, 1501820k free, 173004k buffers
Swap: 0k total, 0k used, 0k free, 1081808k cached

Was wondering how to do this. I was trying to do achieve this from looking at different guides, but I haven't had any luck.
I am on a custom PC, with dual screens; one LCD, and one CRT, from which I installed OS X 10.5.6 from a retail DVD.
I installed OS X first, because I needed to format my HDD to use GUID partition table, because you can't install from a retail DVD without using GUID. Once OS X was installed, I partitioned my hard-drive into 4 partitions from the OS X disk utility. These partitions were HFS. I then used the Ubuntu Lucid x64 Live disk to format the 3 nre HFS partitions to use ext4, for two of them, and one swap. I installed Ubuntu as normal.
I re-booted, and GRUB recognized my OS X instillation, so I tried to boot into it. It went into OS X, but with some major problems. My LCD screen was going haywire, but my CRT seemed to be working, but it took on my LCD's screen resolution and place as the main screen.
I thought my OS X instillation was badly damages, so with Ubuntu still installed on the other partitions, I re-installed OS X, which I am on now.
I want to know how to boot back into Ubuntu, while still having the option to boot into OS X.

I get 3-4 clicks every minute, until I realized the problem and installed "laptop-mode-tools". After that things are back to normal.Why isn't laptop-mode installed by default in Lucid? This is a simple work-around which should be imposed by default, so users' hard discs won't be damaged.
