After updating to 9.10 NBR on my MSI U90 it behaves like pressing the function keys "increase brightness" and "decrease brightness" continuously, including show the appropriate pop up.
I guess it is related to power management because it mainly happens while on battery.
How can I get rid of this problem?
Sometimes, out of the blue, my screen will suddenly change brightness. And no, not the gnome power manager dimming the screen when idle, I'm talking about it suddenly going from dimmest to brightest when I haven't even touched the screen brightness buttons in the last few minutes.
what package would I file this bug against)? This is Maverick on a thinkpad T60, and I can provide any other information that people find relevant. On what may be a related note, it seems that one push of the screen brightness up or down buttons causes two increments in brightness.
I recently installed Debian 8.2.0 on an older machine (circa 2008, AMD Athlon Dual Core 5000B Processor, Nvidia nforce MCP61P Chipset, Nvidia Geforce 6150SE nForce 430 onboard video).
The install went smoothly, but occasionally the screen scrambles (see example below)
I have to force restart every time this occurs, and I'm not entirely sure what causes it. It used to only happen if I launched iceweasel too soon after login, but now it happens at any random time (in the middle of doing an image search, or right at the end of a 6 hour work session without any hiccups. I have only found topics on "screen blanking", and similar issues when using brightness controls on laptops, but nothing specifically like this.
I Install Ubuntu 9.10 and I can't control Brightness, show brightness popup (Fn+F5F6) but screen brightness don't work, I install NVIDIA Driver Linux-x86_64 version 190.53, modiffed xorg.conf.

FN keys and desktop display applet will not adjust the display. when I first boot my display is pretty bright with either it plugged into ac or not until i either plug or unplug for the first time then the display dims some, but will not get bright again plugged or unplugged, also /proc/acpi/video/DGFX/LCD/brightness shows it set to 100% at all times it never changes. I'm using the ati driver tried running aticonfig --acpi-services off, but it made no difference. It worked fine in karmic and ibex. I'm out of ideas on how to fix this one. Can anyone point me in the right direction on what to try next?
View 5 Replies View RelatedI am running Karmic (9.10) on my macbook air (2,1) and although many things work fine (I wrote about it here:[URL]) one of the last things that doesn't work is setting the screen brightness. The FN-F11/F12 combo does bring up the brightness adjustment notification window (top right) and I can change the setting, but it has no effect UNTILL I reboot or suspend to RAM and reboot.
A related issue is that the brightness doesn't automatically adjust to the surrounding brightness.
After manually setting the display brightness on my laptop, the system re-sets the value. If the laptop is plugged in, the value is set to full brightness; if it is not plugged in, it is set to dimmer. How do I stop that behavior?
Note that I am not talking about what it does in response to the event of plugging in or unplugging my system. It changes on it's own - usually several minutes after I change the brightness value. I have observed this behavior on different systems, different distributions, and different desktop environments.
Today I installed debian-8.1.0-amd64 on my older Samsung Laptop (Model r560). The installation without a desktop environment worked fine and the system booted without any problems into the virtual console. There was however one problem: when I was away from keyboard for some time, the screen turned black and when I came back and hit a button to wake the system up, the laptop immediately restarted. Later I installed the gnome desktop environment. This also worked fine.
But whenever I try to change the screen brightness in the gnome-shell, my system immediately restarts and successive attempts to boot debian fail. Some time later and after countless attempts to boot debian, it finally does boot again. By "debian fails to boot" i mean the following: The initial ram disk is loaded and fschk runs. Usually the system suddenly reboots at this point. SOmetimes, however, the video mode changes, the console font is changed and some services are getting started, but then at some point the system also restarts. I don't reach the point where a login prompt appears, or the graphical environment starts up.
Assuming, it has something to do with buggy acpi implementation of my hardware, I tried the following:
I tried to disable acpi completely by using the kernel parameter "acpi=off". This doesn't work and causes the kernel to hang
I tried to start debian without using a GUI using the single parameter. This also didn't work.
acpi_backlight=vendor also did not fix the problem.

I'd been trying to get into Linux before I bought it so I figured that I would try to get it onto my new Mac so that I could use it wherever I am. I decided to try Debian Lenny 5.0.3 a whirl after reading about all the different distros available. I've successfully installed it and I can get to it with rEFIt, and I have quite a few things working such as the video drivers and wifi. However, I've had trouble getting it to a level where it'd be usable away from home. Here are the main problems I'm worried about:
1) I installed pommed but I still can't use the brightness keys to change the screen brightness. I'm not sure if there's some other workaround for this?
2) I tried some recommended power management packages (gnome-power-manager) but it doesn't seem to be accessible or functional right now. I don't have any way to control it or get to it that is obvious to me. Is an icon or anything supposed to appear on the task bar when you install or what? Getting some sort of power management on here is important because it gets really lousy battery life otherwise.
3) Being a Macbook, there's no right-click button. Multitouch would be really nice (two-finger scrolling!) but I'd be OK with ANY way to right-click with the touchpad. I have a wireless USB keyboard/mouse combo that works at home at least . . . right out of the box too!
4) I've seen some packages called the Mactel PPA, but they are made for Ubuntu. Since Debian and Ubuntu are so similar, is there any way to make those work on Lenny? I think that if I got those to work, I could fix some of the problems above. Or do I have to install Ubuntu?
5) I just noticed that the sound doesn't seem to work yet either.
I'm having a really strange problem, when I turn on openSUSE, the brightness is fine.owever, as soon as I log in the brightness gets obnoxiously low. I have a MacBook Pro 7.1 with openSUSE 11.4 KDE

When I plug in the charger, the brightness level is good. I used the Fn up/down key to increase and decrease the level of brightness, but didn't work. I even checked the Power Management section, but didn't work. Installed an app called Ubuntu Tweak which allowed me to increase the level of brightness when on battery, but that too didn't work out.

View 8 Replies View RelatedI could find on the net to fix the screen brightness keys and get them working so I could increase the screen brightness. Nothing worked.For most or many people, some of the suggestions will work fine. For those of you who can't get them to work and are stuck with Ubuntu 10.04 on the NC20 with a dimmed-out screen, I have a quick workaround:
When you boot and get to the BIOS password prompt, use the function and up-down array keys to control the brightness there. The screen brightness will be carried through to Ubuntu. You might be able to do this at the GRUB prompt. The point is that the BIOS handles the screen brightness before Ubuntu, so it just works.
I am a new user of Ubuntu, I use Ubuntu 10.04 Lucid Lynx on my laptop Acer Aspire 4741G and the specification are:

I have a problem in adjusting brightness, before this laptop, I used Ubuntu on my Acer Extensa, all shortcut buttons are working properly, include Fn button. To adjusting brightness, I only have to push Fn button + arrow left or arrow right. And now, I try in Aspire 4741G, it does not work. I also try to type command via terminal:

View 1 Replies View RelatedUbuntu was working perfectly fine, then I used the Update Manager to update ubuntu, but my laptop randomly shut down during the installation (which my laptop has never done before and hasnt done since). When I turned the laptop back on, and booted Ubuntu, a white box appears in the middle of the screen but rather than asking for my login details, it just says what I named my computer. I am unable to move my mouse or type anything on my keyboard at this stage..

The other 'problem' is the MP3 codec? How do I install this? I'm trying to use my Mp3 files in Rhythm box but can't find out how. =[Why does it have to be different ;(
I installed Ubuntu 9.10 on my older computer. Before the installation I used Windows Vista and Windows 7 and I decided to do a clean installation. When I ran Ubuntu from DVD it was perfectly healthy and no problems appeared. After the installation there became random freezes. The system freezes but mouse is still moving and can't do anything else than reboot.
From the other topics I read that it might be a problem with GPU drivers and I heard about this Envy program which might be able to install some drivers but don't know how to install that.
The computer is pretty old:
AMD Athlon 64 Processor 3200+
ASUS M2R-FVM (includes integrated ATI Radeon Xpress 1150)
1 GB of RAM
320GB Hard drive
And I couldn't find any Linux drivers for the graphic card from AMD's internet page.
Last weekend I installed Ubuntu 10.4 (Netbook remix) on my new Acer Aspire 751h. The installation seemed to go smoothly, but I've noticed several things that don't work as well as on my old AA 110. I should say that I installed Ubuntu in a dual-boot setup with Windows XP, which the machine already had installed. Firstly, the screen brightness can't be adjusted with the function key/hotkey combination. The sound volume hotkeys work fine, and the brightness hotkeys work with XP, so it's not a hardware issue. The default brightness is pretty dim, so this is an annoying problem. Is there a way to bind the hotkeys to the 'increase/decrease brightness' functions?
Secondly, the vertical scroll bar on the desktop doesn't work, by which I mean if I click above or below the highlighted area no scrolling takes place. However, I can drag the highlighted area up or down and scrolling does take place, and scrolling via the touchpad works. All forms of scrolling work normally within applications. Is there anything I can do to fix this? It's only a mild annoyance, though. Thirdly, in the power management preferences application I don't have an 'On Battery Power' tab - just 'On Mains Power' and 'General'. There are some other peculiarities that probably follow on from this. I have a power indicator in the top panel of the desktop, but on bootup it's a 'lightning bolt' icon rather than the battery-shaped icon it should be. If I plug into mains power, it changes to a battery-shaped 'charging' icon until it's fully-charged, when it changes back to the lightning bolt. If I then unplug the mains power, I get a battery-shaped 'discharging' icon, but this doesn't survive a restart. Obviously, a battery level indicator is very useful and I'd like to get it working properly. The help file for power management preferences says something about GConf policy keys that need to be made writable in order to display some sliders and option boxes. I certainly don't have as many sliders and options as shown in the help file. I guess this might be related to the screen brightness problem.
Finally (for now - I haven't explored everything yet) the screen ratio looks wrong. Circular icons appear as ovals. It looks like the software thinks I've got a 4:3 ratio whereas really it's widescreen. I can't see where I can change this. I've looked in 'System.. Preferences. Monitors' but there's nothing I can change there. System testing shows the apparent resolution at 1024x768, whereas the hardware spec is 1366x768. I'm wondering whether to try to fix these things individually or whether a better option might be a reinstall - perhaps without the XP dual boot. What do you think? I'm willing to change settings from the terminal but I'd need to be told exactly where to go and what to do.
I have upgraded a friends notebook from 10.04 to 10.10. Everything was fine with 10.04.The upgrade process runed smoothly but after booting 10.10 the X system randomly restarts. It seems to not be able to run for more than 10 minutes without X abruptly restarting and the login page being presented. I still couldn't even identify some pattern nor relate the restarts with some specific software.I've looked in /var/log/messages but there is nothing registered there that seems to be related to this issue.Despite being an old notebook, I don't think it's hardware related because the problem appeared for the first time after Ubuntu upgrade and it keeps repeating itself after that.
View 2 Replies View RelatedI installed Ubuntu as well but was still using the windows loader. I eventually installed Ubuntu Studio when I got another HDD (which is where I installed it). Don't ask me how I did it. As of now no loader automatically pops up. It acts as if there is nothing to boot from. However I can hit f12 and chose which HDD to boot to. On one it comes up with the Windows loader w/ Vista and Ubuntu. I can chose Vista and it works just fine. However if I chose Ubuntu it starts going a lil nuts and restarts. If I chose the other HDD it boots up Grub w/ options of Ubuntu and Ubuntu Studio. Studio works (which I'm currently on) and pretty much the same thing happens as before when I chose Ubuntu. So if the 2 OS's that I need work (Only really use windows for games) then what is the problem? I know its a little bit annoying trying to remember to hit f12 and having to chose your OS again after that (and of course the extremely annoying vista startup times). Some other things in both Studio and Vista don't want to work like they should. This is about the only thing left that I could think of that may have something to do with it. My wireless card+an old wireless card I found won't work w/ either.
Yet they both work on other computers running Vista and/or Ubuntu (not studio). I seem to always keep having display problems on both as well (dual monitors and graphics both). Even on studio I have to restart it sometimes to even get it to let me go fix it. My wireless controller receiver (for games) will stop working randomly and need to be unplugged and plugged back in. I also have problems with Studio recognizing SD cards and DVD/CD's. I am not sure much of anything can be done aside from wipe and fresh install on both. Bad thing is I don't have my other computer with me and can't afford to buy a 1TB HDD right now.
This fixed a black screen issue and a brightness adjustment issue after installation of ubuntu. Also on 11.04 I couldn't get Unity to work until I edited grub I didn't come up with the fix but it took me forever to find a solution so I figured I would post it. If I have did something wrong just get a mod to delete or move this. I don't use forums often.

Suffice to say I had a dual boot at work with an essential windows 7 and non-essential linux install on it, and randomly upgrading the distro made windows7 unbootable. Cue a missed days work, much embarrassment and ear bashing from those who are convinced Linux is written entirely by communists and hippies. In the end I had to re-install windows, which cut off the ability to boot to ubuntu - although I've left the existing ubuntu partitions as they were.
Although I can get away with allocating a few partitions to ubuntu, I can't really justify fiddling with the MBR based upon this experience. I need a fast boot and persistent data for doing anything further with ubuntu at work, so I'm wondering whether a safer bet would be to setup a usb stick with enough grub to boot to the existing ubuntu install? Not a full usb distribution, just enough to boot into the existing install? how this would be doneIs it really just a grub-install /dev/sdXX (where XX is the usb)?
A while ago, when I was using Maverick, Firefox started to crash randomly and led to kernel panics.
So I upgraded to Natty (clean install) and Firefox there too crashed.
Then I was getting graphics and make problems.
Today I tried to install Fedora 15. It first boots to a Live desktop that warned me that my hard drive had 65000+ bad sectors. Sixty-five thousand.
So I got a new one. A WD Scorpio Black, 750GB 7200RPM with Advanced Format.
Again I boot into Fedora 15. OK, no bad sectors. I tried to run Disk Utility Self Tests but it constantly crashed. Fedora warns you about this.
In the Live session, I opened Firefox. It also crashed just like back in Ubuntu. Then the screen flashes black and got warnings after warnings that a kernel module has crashed.
So I took out my old Maverick installation CD and first tried a Live session. However, Disk Utility told me that SMART is not supported while on Fedora, it was.
So I tried to install. But soon after that, I got a warning that the installer has crashed because a file copied to the disk did not match the file on CD. Right now I am in the Maverick Live session.
I'm trying to install Wheezy (amd64) from the daily netinst image with the text-based installer. The PC will lock up randomly at some point in the process (usually after about 5-10 minutes). The video signal cuts out, keyboard lights are unresponsive, and I have to hard-reset the machine.I was previously trying to install Linux Mint Debian Edition and had the same problem. Another user reports that this is due to a bug in the nouveau nVidia driver, but I can't confirm it.URL...
I assume the Debian text installer isn't using nouveau, so it seems unlikely that would be the problem. The random timing does suggest an overheating problem, though, and the fact that the video signal drops out would seem to implicate the video card. I had no lockups at all with the OS that was previously installed (Ubuntu 11.04).
I installed Linux yesterday alongside windows vista. Everything went very smooth. I restarted the computer multiple times without issue, and the menu would pop up asking me which os to load. Everything was good. But today I attempted to boot up my computer and nothing happens. The screen just stay black. The lights come on on the laptop, but nothing else. Either I try to boot it and it goes on then off quickly, or it just sits there, still on, with a black screen. I don't know if this is related, but when I was messing around with ubuntu yesterday after I installed it, it would randomly freeze and my caps lock light kept blinking on and off. I was forced to restart when this happened and then everything would be ok.
