Ubuntu Multimedia :: Disable 3D (dri) In Lucid / Switch Off 3d Dri On Laptop To Save Power?
Jul 25, 2010
I want to switch off 3d i.e. dri on my laptop to save power. There is a bug in the intel video driver that makes it generate excess wakeups and thus increase power consumption. I don't use 3d so this is very annoying.
I have tried modifying /etc/X11/xorg.conf to insert an "NODRI" option in the "Device" section and have commented out both of the "load dri" commands in the "Modules" section. No go. When I look in the xorg log, these changes are seen but not acted on. The system appears to have hardwired defaults set somewhere which are difficult to override. It appears to be a new issue because with Karmic one still had control with xorg.conf.
Just generally I don't like changes like this because it is not documented on the wiki where and how to change the defaults in Lucid. Linux was supposed to be easily configurable so IMHO this is a step backwards.

I have HP Compaq 6530b laptop running Debian Wheezy AMD64. I have a docking station with a monitor supporting 1680x1050 resolution and the laptop monitor with 1440x900. The video is integrated Intel mobile series 4.Both monitors are identified and working OK. When I use the laptop monitor standalone it runs at the native resolution. When connected to the docking station I can choose dual monitors with both using their native resolutions and the desktop spread on both of them (with the laptop monitor being primary and containing the taskbar and icons). If I choose to mirror the display it sets itself to a lower resolution of 1280x1024 that is supported by both monitors.
The problem is that I want to use one monitor at a time. If I close the lid of the laptop it turns off both monitors instead of using the docking station. When the lid is closed I want the bigger docking station monitor to be primary and working at native resolution and if I open the laptop or remove the laptop from the docking station to use the laptop monitor at it's native resolution.I had Debian Lenny I386 before and it was operating as expected but I made a clean install of Wheezy amd64 and I don't know how to configure it.I don't have xorg.conf file so I don't know where it takes the settings from.

I have tried to use the extensions toggle-touchpad and touchpad-indicator that claim to be able to do this, but neither will load properly. They show up with a little exclamation-point-triangle in the "Tweaks" panel saying "Error loading extension". How to get Jessie gnome system succeeded in getting their touchpad disabled via a simpe toggle mechanism?

I recently upgraded from Karmic to Lucid via the Update Manager. I would like to upgrade further by switching from 32 Bit to 64 Bit. I downloaded the Lucid 64 Bit ISO and wrote an install disk. When I reboot the computer with the install disk nothing happens.

I Have been "dual" booting two O/S's independently on two hard drives, and it has worked perfectly although a bit of a chore having to go into BIOS to select the other drive if I wanted to swap. I do it this way as it stops all the headaches with the MBR or GRUB, and doing updates and re-installs are completely clean and hassle free(what % can claim this in a regular multi-boot?) I have at last found a power switch to make the whole process even easier, its a simple 3 pole switch that slots into the front panel,searched the net for weeks as I knew they existed but only in the USA or Taiwan, managed to track one done in France,I thought I would share this information as I think it gives a simple solution to a what can be a very complex and frustrating problem![URL]...

Out of nowhere my computer will not boot up. I get the message like this
NMI received for unknown reason 29 on CPU 0.
Dazed and confused, but trying to continue
Do you have a strange power saving mode enabled?

On a couple of Linux laptops I have the built in screen never turns off it's backlight, regardless if a 'black screen' sort of screen saver is activated (this both for a laptop running an X-based desktop as well as for a laptop only having a text console) or if I even close the lid of the laptop (looking carefully in the dark, I can tell that the screen still has the backlight on, even if the laptop "know" it is closed).
This is a bad thing for a couple of reasons:
It wastes power
It generates heat which when the laptop lid is closed increases the cooling need (the fan goes on more often etc).
Backlights have limited lifetime like all electric components and IIRC, the less a backlight is turned on, the longer it will last. So, what is the best approach (considering a Gentoo with a 2.6.36 kernel) to remedy this? I recon that there probably are two approaches:
One for text-only laptops which never displays a desktop, e.g a laptop sitting there acting like a firewall or server
one for those running a Gnome/KDE/XFCE desktop (and a SLIM or GDM display manager).
The laptops I have in mind is a Dell Latitude CPi (built 1999, yes, it is from another millenea), a Compaq Armada M700 (built 2001) and a Dell Latitude D630. If this can be accomplished only by configuring things in the Linux OS (be it kernel setup or editing config files) without touching anything in BIOS, that would of course be preferable.

I have a server that only runs durring the hours the house is asleep, to avoid bandwidth hogging. I know there are ways to prevent bandwidth hogging, but I figured I'd kill two birds with one stone. My other goal is also to reduce power and cooling costs. My two computers between them make a very nice space heater in the winter, in summer they make it sweltering in my room.I'm sure it would be trivial to get the sever to power itself off every morning, but is it possible to get it to power itself on at bedtime? If not, I do have Wake on Lan working, is there a windows program that would allow me to send a wake on lan signal every day and then shutdown windows

I have created a custom linux distro originating from the ubuntu server edition and have slim as the login manager, and openbox as the window manager. When it goes into power save mode and turns off the monitor and I move the mouse to wake it up it just goes to the shell with a mouse cursor on it. How can I get it to go right back to the openbox window manager?

I have a Dell Precision T3400 workstation (Nvidia Quadro NVS 290) with the kmod Nvidia driver installed. Everything works fantastic for power saving, the screen saver comes on , then the monitor blanks after a while. The only problem is that the monitor itself (Dell E228WFP) never goes into standby. The power LED stays green instead of orange. Worked fine under FC8, only noticed it recently under FC10.

I'm not sure this belongs in this forum as opposed to the hardware forum, but I do not beleive this is a hardware issue.I want to stop the scrren from blanking and going to power save. I'm running 5.3_x86-64 and I'm using the nVidia drivers direct from nVidia called NVIDIA-Linux-x86_64-96.43.13-pkg2.run.
So far, I'm added DPMS off in /etc/xorg.conf, removed all the screensaver packages and all the power management packagesbut the screen is still going blank after a time of inactivity.What else do I need to do? I can not allow the screen to go blank, there should be no screensaver or power management and the machine should stay in a completely awake and ready-to-use state at all times.

I have built a Centos 5.3 server for a friend of mine that is being used as a NAS server. The server has 4 1TB drives in a RAID 5 configuration and a dedicated non raid system drive for the OS. My friend isnt very Linux literate so I need this bow to be relatively simple. I have worked most of it out but have a question with regards to remote reboot.
I need to be able to shut this device down through the power switch without human intervention (at the moment when the power switch is pushed the server asks to confirm shutdown) the server wont have a Monitor connected so this isn't practical. Is it possible to use the power switch to do an clean, immediate shutdown?
The other option is shutdown through a web page is this something that has been done before? I know he can do it through terminal by issuing a shutdown now command but as I said this guy wants something simple. I don't really want to explain everytime he needs to shut the Server down how to do it if he can just do it via a website or even with the power button.

I use Squeeze with Xfce. My problem is that recently (after the xfce updates) the xfce power manager doesnt react to the power button - it is set to suspend. I dont have gnome-power manager or anything like it running.
If i reboot the computer, the power button will work but if i suspend and resume, it doesnt work again.
The computer is built on an Asus M3N78-VM mobo (2GB RAM/Athlon3200+ single core).
acpi_listen detects the button press.
Any thoughts?

I recently installed the first non-virtual Ubuntu server in our office (to put it in perspective, it's outnumbered several to one by Windows servers). It had an inexplicable array failure, and now it's been retasked to run VMware Server for testing purposes since we don't trust it at the moment. For the sake of ease of use, on this server I decided to install Xubuntu desktop x64, rather than Ubuntu server as I've done with a couple others.
This server is on an old school 8-port Linksys PS/2 KVM. It's got a CRT monitor in the middle of a rack of somewhat aging equipment. The problem I'm having is somewhere between the KVM, this old monitor, and some power saving... when Xubuntu tries to put the monitor in standby, instead it gets this vertically scrolling garbage. The Windows servers in this rack don't have any problem putting it to sleep, but I figured I might as well just turn off DPMS on this particular server.
So I logged in via SSH, stopped GDM, generated a /etc/X11/xorg.conf, and changed Option "DPMS" to Option "NoDPMS" which according to the manpage should take care of it. I also changed the GDM video mode with this xorg.conf so it's definitely being used. Following some other suggestions I found in my search, I issued "xset s off" and "xset -dpms" but this hasn't disabled monitor power saving either. I've been restarting GDM each time I change something. 5-10 minutes later it's scrolling garbage again. What's it going to take to turn off monitor power saving at the GDM logon screen?

Ok so I am a total newbie at Ubuntu Linux and I'm having problems I don't know how to solve.
1.) Up until yesterday this wasn't a problem, but after a power outage while I was connected I am now unable to connect to the internet anymore as it says "Networking is disabled", how do i enable the "networking"?
2.) Another problem I am having is that I am not able to dim the screen in order to save power among other uses, I've looked around but haven't been able to find a solution, I am running ubuntu on a Gateway M-Series Laptop.
3.) Finally, since installing linux I have been unable to listen to music or any other sounds through headphones or speakers, when i connect something into the audio output, the outer speakers do shut off but no sound is emitted through the speakers/headphones, and yes i have tried multiple ones to make sure it wasn't the headphones or speakers.

I am using Xubuntu 9.10 on a nettop as a X11 terminal.In order to do that, I created a custom session script that runs some commands instead of starting xfce4-session and the likes from GDM. When I boot this nettop, GDM automatically logs a dummy user in (called "test"), and runs a script that does "xhost +", and opens a small X Terminal to keep the X session alive, while some other computer sets the DISPLAY environment variable to point to <nettop>:0 and runs gnome-session.
My trouble is that after 10 minutes of idle, the screen is blanked(power saving I presume).
I tried to add "xset -dpms" and "setterm -blank 0 -powersave off" to my startup script, in vain. I want my power saving options to be configured on the remote computer, not the nettop. How could I prevent X/GDM/Whoever from blanking the screen ?

I need to disable the automatic power-off on shutdown so I can just withdraw the power myself. The reason for this is that the machine should power on itself when it gets power (which is accomplished by Resume on Power Failure in BIOS). I learned that I can turn off ACPI and APM by using the corresponding boot command options. Does this have any negative effect other than disabling standby etc.? Is there another easy to accomplish solution for this problem (maybe using linux from a readonly partition and make sure all programs are closed before I withdraw the power)?

running PCLinuxOS 2009.1 on my main machine : AMD Phenom II 545, 3GB DDR2, ATI Radeon HD 4870 512 GDDR3, 1 x 250GB IDE, 1 x 1x 250 GB SATA, 1 x 160GB SATA, 1 x 500GB SATA.What I want to disable are the HDD's powering down after a while because when I come back to work at my machine, it is painful to wait for the HDD's to spin up again. I also want to disable the screen from turning off. I have removed DPMS from myxconfig, but it as made no difference.

every time this boots now, I get that message. If I hit cancel, then the screen locks and the mouse moves but nothing happens. The only way to get it show the desktop, is to select 'logout anyway'
Plus the boot takes forever at least 4 times longer than karmic.
all of this is in reference to booting up the PC

I've installed lucid on two computers now and have been using or a few months.Overall, it's pretty good and everything just works. However, every now and then (seemingly random), the power button in the indicator appletsion panel widget randomly disappears, so I'm unable to shut down my computer without re-adding the widget, or using the command line to shutdown the computer. Now this is acceptable for me, an advanced user. However, this is not acceptable for my parents and family, who also use ubuntu computers. Today, my mother called me to ask why she couldn't turn off her computer. I was dumbfounded, and had to walk her through turning it off "by hand."
Now this is not me accidentally removing the indicator applet session panel item. No, I can still see the user name bubble with availability information and I can still switch users. It's just that the power button is completely missing (sometimes the place where it used to be is occupied by a corrupt graphic). Additionally, if I login later, the power button magically returns without me having to do anything with regards to the panel. This is disappointing indeed.
Honestly, this is why ubuntu and linux in general still have the reputation they do of being non-user-friendly. At least in windows or mac, when I get fed-up I can turn it off. But not so in ubuntu. No ubuntu tortures me continuously and I marvel that such a simple thing has escaped the minds of such advanced programmers. I wish Canonical would focus on letting us TURN OFF the computer instead of adding crazy features that I'm not going to use. I mean how can a real operating system fail at such a simple task

Having a bit of an issue with my Lucid x64 HTPC. I can get the image to appear through DVI on a spare external monitor, but when it is disconnected and switched back to HDMI I get not picture on the TV any longer. I switched the sound output to an external USB device for testing the unit and noticed on reboot that I had lost everything via HDMI even though the setting had been switched back previously. Obviously a setting must be off here somewhere, but I've yet to find it. I've rebooted with only the HDMI connected, but still nothing.

Once again, nobody seems to understand security properly when they decide to add nifty new features. After upgrading to 10.04 from 9.10, I now have a listing of all the user accounts under "Switch from" when I go the the logout menu at the upper right side of the task bar. This is a terrible security hole that should never have been allowed in the first place, and is just as annoying as the default behavior of listing all the user accounts on the login screen.

I've just installed openSuSE 11.2, and I need to disable the feature that causes the laptop to suspend when you close the lid (and it's plugged in to the wall). I've already done this for my user profile, and I've attempted to do it for the root profile, as well, but when the GDM login screen is shown, the laptop still suspends when you close the lid.
