Ubuntu :: Dim Screen - Cannot Change Brightness Settings On Netbook

Nov 18, 2010

I bought a Asus eeepc a few days ago which I really like, with the exception of one thing - windows 7 starter. I like Windows 7, but starter is just bad. I also really like ubuntu, so I've decided to put it on my netbook. I download the netbook edition from the site, put it on a usb drive, and than tested it out - well, my screen is dim, very dim. Changing the brightness setting on the tool bar up top doesn't change anything, and using the function keys does change it, but still keeps it very dim.

I've tried restarting my computer, same thing, I've tried messing around with settings in the battery options, nothing... I really don't want to install it if its going to be this dark, I can see things, but its not very pleasant to use. I'm starting to consider that its the problem with the file I downloaded. Theres nothing wrong with my netbook, everything worked perfectly fine in Windows 7. I use the full version of ubuntu 10.04 on my other laptop which works perfectly fine, I'm not sure why this version is acting so weird on my netbook.

Debian Hardware :: Getting Lenny Working On Macbook / Can't Use Brightness Keys To Change Screen Brightness?

Feb 9, 2010

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.

General :: Unable To Adjust The Brightness Of The Netbook Screen?

Apr 19, 2010

Long, sad story made short. I have a Samsung Netbook running Windows XP Home, SP3. I set it up to dual boot with Ubuntu, just so I could play around with Ubuntu. Well, Ubuntu started giving me trouble: my internet connection went south, I was unable to adjust the brightness of the Netbook screen, etc., and when I looked for troubleshooting help on the internet, it was all Greek to me as it involved working with Terminal.

I did a search for removing a partition in Windows XP and found "How to use Disk Management to configure basic disks in Windows XP" on the Microsoft and followed the instructions there.

Fedora :: How To Change Screen Brightness?

I'm having trouble locating a way to adjust the screen brightness on fc10... It is only possible to use the monitor's control for now.Yeah my monitor make an annoying whining noise unless you turn it on 100% brightness, but that hurts my eyes.It is so crazy that they didn't put a brightness control in! ( or rather they destroyed working ones of year past, Why? )

Ubuntu :: Screen Resolution Settings For Netbook?

Aug 15, 2011

I've got a Disney edition Asus EeePC with an xp/9.10 nbr dual boot.The 9" screen has a native resolution of 1024x600, but in xp it can expand that to 1024x768- either by scrolling the desktop up and down a bit, or by what they call "LCD Compress" mode, where ever thing gets squished vertically a bit to fit 768pixels of info in 600 pixels of space.

My daughter uses it to play games on webkinz.com, and their games pop up on a 800px high non resizable or scrollable window, so there are controls and junk that fall off the bottom that can't be reached unless I'm put it in one of the 768 pixel modes. That, and with her task bar set to auto hide, she can play games and have a good time. how do I set up Ubuntu 9.10 to do the same thing? Right now, the only screen resolution in Ubuntu is 1024x600.

Slackware :: Ctrl+up|down Don't Change Screen Brightness Any More

Jul 16, 2010

i had slackware 13.0 on my dell vostro 1320 and it was all good, but since the upgrade to 13.1 i cannot change the screen brightness with ctrl+up and ctrl+down keys..i'm not even sure how to start with this problem. from what i understand these keys 'call' a bios function...? so that would mean that some kernel module is not being loaded?or has the desktop environment lost the key mappings and that is causing my trouble?

General :: Bind Certain Keys To Change Screen Brightness

Jul 19, 2010

I am using Ubuntu linux, and I want fn + up key and fn + down key to change the brightness instead on fn + F4 and fn + F5. I've tried looking for something in the Keyboard Shortcuts menu, but there is no command or key specified to do that. I could make a custom key shortcut, but I can't find the command to change the brightness. Is there a way to make another key do this? My laptop is a Dell Inspiron 1545.

Ubuntu :: HP Touchsmart Tm2 - Synaptics Touchpad Is Unusable - Change The Brightness Will Kill The Screen

Dec 17, 2010

I installed Ubuntu 10.10 on my laptop and encountered several issues.

1. The Synaptics touchpad is nearly unusable. It is impossible to drag while holding down a button. The cursor will move randomly across the screen instead. It is impossible to right click; a right click is treated like a left click. Double-tapping the dot in the corner does not disable the touchpad.

2. Attempting to change the brightness will kill the screen. The computer is still functioning, and it is possible to perform tasks "blind." Only the screen becomes completely blank.

3. Ubuntu does not always boot up reliably. When it does not, the screen is blank but the computer is otherwise responding.

4. The screen is black after suspend.

5. The computer will sometimes hang when shutting down (showing desktop background). Possibly related messages in dmesg:

Slackware :: Cannot Control Brightness Settings On Vaio - 13.37

May 11, 2011

I just finished installing Slackware64 13.37 on my Sony Vaio PCG-7153L, and I'm having issues controlling the LCD brightness of the laptop. It still has the stock Slack kernel 2.6.37.6 SMP The brightness controls worked on Fedora 12-14, as well as the Ubuntu 10.04 live disc. I checked /proc/acpi/, but there's nothing in there to control brightness. I reloaded the sony_laptop kernel module, and from dmesg I get:

Code:

sony-laptop: brightness ignored, must be controlled by ACPI video driver From the Ubuntu bug [URL] and the Red Hat bug [URL] it looks like they've already dealt with this problem. However, as I said earlier, my laptop worked fine with Fedora 12-14.I know Slackware does minimal fiddling with the kernel, so I'm thinking this might be an upstream kernel bug...

Ubuntu :: Change File Permission Settings To Force All Documents To Inherit Parent Document Settings?

Aug 21, 2011

i have a computer with 3 users on it, and a folder using samba that everyone on the network has access to. Lets say that, the folder is stored in /etc/sharedfolder. What happens is, when user1 puts a folder in it, then logs off, user 2 attempts to modify it and fails, because permission is set to 755, and they are not in the same group. (even if they were, it should still need to be 775) Anyway, my current solution is, every 5 minutes a crontab changes permission like so: chmod 777 -R /etc/sharedfiles && chown useradmin:superadmin -R /etc/sharedfiles Which works, but seeing as there is getting close to a gig in there, this is a bad solution, as it eats up the computers resources. Solutions that i think might work:

1) create a script that only changes permissions that need be changed.
2) change file permission settings to force all documents to inherit parent document settings

Fedora Hardware :: Not Possible To Change Brightness

Jul 29, 2011

Recently, I installed Fedora 15 in my Sony VAIO Laptop Series E. Firstly, I had a little problem with nvidia drivers and wireless because I installed from a normal CD, but then I repaired it installing drivers from the web page and updating the system. However, I continue having a problem with changing brightness even with the Fn buttons or with the gnome configuration control. I followed some suggestions as for example these ones http://forums.fedoraforum.org/showthread.php?t=262545, but nothing change. I already tried with xbacklight but still not working. I also did a change in grub conf file (following google search suggestions) adding these commands: acpi_backlight=vendor acpi_osi=Linux, but nothing.

Ubuntu :: Easy Web Filtering - DNS Settings Don't Appear To 'stick' Once The Netbook

Jul 30, 2010

I've been trying without success for the past couple of weeks to setup a filtering system for my little sister's netbook. The main problem I've been running into is inconsistency. First, I tried using dyndns per the instructions here: [URL] The problem with this is the DNS settings (and in turn the filtering settings) dont appear to 'stick' once the Netbook touches a different network. So if I sign onto a different wireless network than the one I used to set up the filtering, it stops working. The reason why is Ubuntu will overwrite the current DNS settings with those of the new network (I have no idea why, and am too frustrated to figure out).

Also, I noticed that even if the settings did stick, they're fairly easy to disable because all she has to do is stumble across the DNS settings, change them back and voila. I've had great success with OpenDNS on Windows boxes, but there doesn't seem a to be a feasible way to apply it to Ubuntu. Dansguardian looks like it may be worth a shot, but I've seen dozens of "simple" configuration guides, none of which that actually looked simple. So my question is this, what is the easiest, most bulletproof way to setup web filtering 10.4? Preferably something that a 12 year-old could easier find her way around.

Ubuntu / Apple :: Screen Brightness Permanently 100%?

May 11, 2011

I originally installed Maverick on my Macbook 5.1 using rEFIt to dual boot. For some reason, after installing Compiz my screen brightness functionality stopped working. It was permanently 100%. I thought that upgrading to Natty might work, but no luck. So far I've tried changing the brightness manually in terminal and in power-management, editing the grub file and also reinstalling compiz, all to no avail. Trying to alter brightness using the fn keys displays the brightness panel in the top right, and it decreases in value as it should, but the screen stays bright. The brightness settings work fine when I boot to Mac.

Ubuntu :: Screen Brightness Randomly Changing?

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.
