Ubuntu :: Brightness And Contrast Controls Not Available
Aug 20, 2010
I have a fairly new Samsung 2233RZ 120hz lcd hooked up to a GeForce 8800gt...
When i click on the Brightness and Contrast controls on the monitor it gives me "Not available"...
Does the linux nvidia drivers disable my monitor functions? is my monitor improperly configured? do i need to take some steps in setting up my monitor? there are some tiny white scanlines going through the display horizontally if i look real close...minimimalist ubuntu 10.04/XFCE4 same happend on ubuntu 10.04 gnome... with or without the geforce drivers.
since I installed ubuntu 9.10, my video files, specially .avi, are showing up on every player with a high contrast or too much brightness... So i have to go t vlc and adjust the image... =/ I'd like to know how can I make the video files running normally as I used to do at 8.10...
Im using ubuntu 10.04 I would like to know if their is a program that can change the format, contrast, and brightness of a large bulk group of pictures instead of doing it one by one?
Sometimes while watching ..... vids in firefox I often want to adjust the brightness/contrast/saturation levels.I didn't see any addons for the purpose.Is there a way to do this ?I have visited web sites with embedded flash players which includes these controls.
I took the courage yesterday to install ubuntu 9.10. Internet was working absolutely fine (wireless), but brightness controls were not working (they still don't). So I went to this page https://wiki.ubuntu.co/Hotkeys/Troubleshooting, and ran following command(s) killall gnome-settings-daemon gnome-power-manager Now since then I cant get the internet working, and cant see the wifi connection on task bar. I have restarted the laptop but no avail.
PS: any help on how I can reduce the brightness of monitor. I am using SONY VIAO VGN FZ38M, with Nvidia 8400M GT. I have tried several threads and tried all sorts of things, like xbacklight, or somthing to do with sudo .VGA/LCD/brightness.etc.
I recently purchased an HP Pavilion dv7t 6163us and I installed ubuntu 11.04 on there. Everything works fine except the fn + f2 and fn +f3 which decreases and increases the brightness respectively. It's using the i7-2630qm sandy bridge processor and intel HD graphics 3000.
Recently I tried putting Kubuntu Natty Narwhal on yet again and to my surprise it mostly worked. The only major thing wrong with it was my brightness controls didn't work (I have a VPCCW21FX laptop) at first this was an anoyance being blinded by my screen but I soon realized that it was killing my battery life. So having tried to seek help in getting it to work I tried out OpenSUSE. They worked! but as soon as I updated the kernal they no longer worked. No Problem. I reinstalled and told it to never apply that update. Then I installed the official nvidia drivers via repository on the opensuse wiki. they installed and worked but my brightness controls were once again broken.
I have an Acer 4810T laptop with Intel graphics. I run openSUSE 11.3, and am about to upgrade to 11.4. But both systems still have a very bad bug with screen brightness. The Fn+Arrow keys do change screen brightness, but after using them the system is rendered extremely sluggish and unresponsive. This sluggishness is most pronounced with a very important Wine app I need to use. The only way to fix the sluggishness is to reboot. With 11.4, the problem is worse because the system boots and automatically partially dims the screen, thus making it even more necessary to change the brightness. Neither Gnome nor KDE are able to change the brightness via their power managers. This means that I can't dim my screen automatically upon disconnecting the A/C power.
I have read many experiences from Ubuntu and openSUSE users, who all have the same problem. I have tried both intellegacy and the new intel drivers, and they both have the problem. I have read that some users have improved the situation by upgrading or downgrading the BIOS. Others have been experimenting with kernel patches:
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.
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
I'm enjoying the default 10.04 theme, but the one thing that doesn't work for me is the scrollbar. I can hardly see it. Where I can edit just the scrollbar color without changing themes completely?
I have noticed on a couple of the newer installs I have done, that the Skydome image is faded. It appears to have about 35% lower contrast than it should. I always use the same one, I have compared it to the local file, I am a professional photographer, so I can say it has nothing to do with the image itself, but rather it is some hidden setting somewhere, as I have tried cranking up the image's native contrast, and nothing changes.This happened before, and in the course of normal compiz tweaking, it went away, but I would like to figure out where that is, as CCSM has so many settings, and it may not even be a compiz setting, but rather a system setting. I just do not know.
I am trying to take a color photo and make it a high contrast black and white image. Just a 2 color image; rather, I just want the outline and nothing else.
When playing dvd's, vob files and wmv files, the image comes with high contrast colors ,very intense red/green/blue. very dark too. I have vlc 1.1.4 installed, using ubuntu 10.10, libdvdcss2 installed. for the rest of the video formats it seems to work fine. any ideas on what should I start debugging?
I upgraded from Ubuntu 9.10 to Ubuntu 10.4. After the upgrade I noticed the entire title barding the window controls to minimize/maximize/close a window disappeared.Resizing/moving a window is not possible either.At first I thought something went wrong with the upgrade, so I did a full reinstall, but using the same home dir (sda5 mounted to /home). The problem remains.
I can temporarily fix it by changing the visual effects to normal or extra, but each time I restart I have to do this again. The controls appear at the right side, opposed to the left side which I would have expected from this release.I realized that this must be something in my home dir, so I created a new user. For this new user, everything appears as expected, so it's most likely some configuration file left from 8.10 which 9.4 doesn't like
I am considering installing Ubuntu on one of my desktop pcs used by my daughter. It's currently running Windows 7 32bit in a LUA, but is not as stable as I'd like. I am using Cyber patrol as a parental control system - which could be causing some of the instability. Is there any Parental Control software available for Unbuntu?
I can't get flash controls to work. If the video auto-plays, it starts just fine, if not, I'm out of luck. I've tried reinstalling flash through the software center. Even if it autoplays, I can't control volume or pause or anything. I'm at the mercy of whatever is already there. Ubuntu Karmic 9.10 - all updated as of 1/2/2009 Firefox 3.5.6 On a Lenovo Thinkpad R400
It has never worked. About to pull my hair out and/or reinstall Ubuntu Completely since no one else seems to have to problem.
a widow with 4 kids - 2 of whom have severe depression & signs that one may be suicidal and is taking interst in some dark garbage on the net. Overall still a pretty good kid, but he surely doesn't need help online to get further in a hole. The 15 year old boy is highly intelligent (whole family actually) and knows how to get around software parental controls with peer to peer, live disks, etc. There are several PCs - both windows and mac, and an X-box.
I want to set up the household with a router or similar solution that is smarter than the kid and his friends. I figure protecting the network is the most tamper proof, all-encompassing way to go. In the short term, I really want to lock that home net solid, while still allowing mom to do her facebook and the oldest to use the web for schoolwork. Dlink Securespot technology seems to be the best overall solution I have found so far. If there is something better, I'm hoping someone here can steer me to it.
Yesterday I adjusted the position of the windows controls back to what it was before, by using the configuration editor to set apps / metacity / general / button layout to "menu:minimize,maximize,close". At the time everything seemed good, the buttons moved, and it all worked. This morning I rebooted back into Lucid Lynx Ubuntu 64 bit, and now I find there are no controls on the windows, and I cannot even click and drag them, or double click the title bar to maximize! I checked, and the string I altered is still the same. I can still move windows with Alt-F7 and the mouse, and can resize by dragging out the bottom right corner.
Is there an app I can put on my website hosting server that will do the following:
1. Allow the user to view a DVD. 2. Pause / stop to view something in more detail. 3. Rewind to view something again. 4. Mark location so they can return to viewing in the same place at a later time.
I belong to a fly fishing club. We have tapes of fly tying sessions dating back to 1992. Since we are registered as an educational charter with the state, I would like to make the available to our web sight viewers for learning. The club owns all these tapes and they were filmed at club sponsored functions. There should be no copyright problems. I am in the process of converting them to digital.
I have both a 64bit 10.04 install with firefox 3.6.6 and flash player 64bit version 10 and a 32bit 10.04 netbook edition with firefox 3.6.6 and flash player 10.1. They both are missing the overlay controls.Here's an example link:The pbs kids site has the "BIG" button which allows me to go fullscreen, but then I just get audio on the 64bit machine. I haven't tested that on the netbook version yet.
I was wondering if anyone knows of an upload manager, either native or wine, that allows the control of upload speed? I have one of those broadband plans that severely restricts upstream bandwidth, and while I'm uploading there is no room left for upstream communication, so I can't do anything else online but upload (boring). If I can limit my upstream speed to, say, 20KBps, it essentially frees all my downstream bandwidth and I can actually use my computer.
Currently, I've only tried plowshare for uploading, and though it seems to work well, it doesn't allow shaping...
I have an Epson Perfection V200 Photo scanner.It works as you would expect in XP.In Ubuntu, using the flatbed, not the transparency scan, real whites (white paper backgrounds) come out noticeably blue.This is annoying anyway & especially when printing afterwards.Note that even the scanner white background (left) is blue.The dark blue (right) is where the paper pulls away from the glass when it overlaps the scan area.Many of the other applications have several colour-correction tools, but I didn't find any simple way of using them to fix my problem.
Is this a common problem?Is there any way I can dial it out, once & for all?Or an easy way of using the controls in iscan or AcquireImages?
I downloaded Telerik.Web.UI_2010_2_826_Trial.msi. installed wine.then while running msi file "Installation error" is coming for telerik rad controls. i want to use telerik controls in mono 2.4. how can i do it?
Does anyone know the name of the program that controls the transparent pop-up notification when using programs like rhythm box or pidgin? I'm just searching for things on it but I don't know the actual name of it. Whilst I'm here I suppose I might as well tell the actual problem: Is there a way to get Kmess (no I'm not using Kubuntu) to use the pop up notifier?
