OpenSUSE Hardware :: Acer Aspire 4810T Laptop - Hardware Brightness Keys System Slowdowns, Software Controls Don't Work
Mar 14, 2011
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:
SOLVED (for my laptop at least - Acer Aspire 5740)
The trick was to add "acpi_osi=" (without the quotation marks) to the GRUB parameters. Setting the parameter to an empty string means that no OS is reported to the BIOS. By default acpi_osi is set to Windows NT. I had previously tried "acpi_osi=Linux" but it didn't work, apparently it had to be an empty string.The brightness keys work now I think it might work for other models as well if they have core i3 processors.
I have installed Xubuntu 11.04 on a HP Probook 4510S and the FN Keys of brightness only works when I on the login screen (gdm). Until I enter to my desktop the FN Keys stop Working. This is a XFCE Issue? I have another Laptop, a IBM THinkpad X40, with the same Xubuntu 11.04 and the FN Keys works perfect! Even the keyboard light Works! I think this is a ACPI related problem, I google it the problem with out a specific issue like this. The only thing that I can do it is use of xbacklight when I'm on my session.

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 am a new user of Ubuntu, I use Ubuntu 10.04 Lucid Lynx on my laptop Acer Aspire 4741G and the specification are:
1. Intel(r) Core(tm) i5-430M Processor 2. Intel(r) HD Graphics 3. 2GB Memory 4. HD LED LCD
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:
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.
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.
Code: sudo gedit /etc/default/grub Edit two lines to read as follows:
I recently bought a new Acer Aspire and installed Lenny, I can get a wired network/internet connection however not a wireless connection. I use wicd. Bluetooth doesn't work either though I suspect that it might be the same issue.
Don't know if it helps however when I tpye iwconfig I get: ladb:/home/nigel# iwconfig lo no wireless extensions. eth0 no wireless extensions.
I have an Acer Aspire 1410 laptop which was running Win7. The laptop lacks a DVD drive and came pre-installed with a recovery partition as well.I've been searching for ways to dual-boot Fedora on it. I bought a Samsung USB DVD drive, but I burned two copies of Fedora 12 and neither would boot, nor would my Knoppix Live CD. I even updated the bios. Then I tried liveusb-creator from my desktop Fedora 10 system, but I would still run into strange errors that prevented booting into the installer.
Finally I downloaded UNetbootin and created a USB stick to boot Fedora 12. Neither Fedora 12 nor Ubuntu would recognize my network adaptor for some reason. Undaunted, I then used UNetbootin to create a Fedora 11 image which got me into the boot installer for the first time. I then used my Fedora 12 image from my portable DVD drive to install. The install seemed to go well.
That is, until I rebooted. Grub came up as expected. Fedora 12 runs into a very early Kernel panic (not syncing: DMAR hardware is malfunctioning) within moments. I tried rebooting into Windows, but it apparently doesn't care much for Grub. It sends me into the Recovery software and asks me to reset my hard drive. I've tried that a couple of times now and it's useless. Is the problem with Grub? I thought it would play nicely with Win7 and at least allow me to boot into it, which is why I allowed it to overwrite my MBR. I lack a Win7 disc and cannot repair the MBR that way.
I upgraded my wife's old Acer Aspire 1350 laptop to Lucid Lynx, which works fine, except for the fact that the splash screen both when the OS boots and is shut down is completely garbled and unreadable. The screen is also unreadable when accessing a tty via CTRL+ALT+F2 etc. The GNOME desktop resolution is completely unaffected and is perfectly usable. The splash screen works on MY desktop PC, but it does seem to be using some strange video timings, as my monitor recognises it as 640x480 but doesn't seem able to centre the screen properly. I strongly suspect that this is the cause of problem and my wife's laptop display just does not like the video mode. If I plug my wife's laptop into my monitor, it displays OK.
I have a laptop Acer Aspire 4551-2194. I've installed Debian Squeeze with XFCE and it works great. I have only one problem. I can go through hibernation / suspend, but when I push the power button, the computer hangs. It doesn't come back and I must reboot it.
I have tried the following techniques to try and boot from CD on my Acer Aspire 5515 laptop: Change SATA information to Native in BIOS. Set the Boot order for the CD/DVD Drive to start first, along with Main driver starting second.
My laptop is an Acer Aspire 5515. BIOS Version is V1.0 (latest) from Acer. PhoenixBIOS bios (?).
I have still not been successfully able to boot from CD. No matter if it says to boot from CD/DVD Drive first, it skips on to Main driver and starts Windows. It's not because I didn't burn the .ISO image right, because it worked on my desktop, which is ALSO an Acer, an Acer Aspire T180. What I am trying to do, is install Windows XP Professional, and dual-boot it with my Windows Vista. Only thing is, it WON'T boot from CD.
I newing to utilize linux I want to ask I install redhat enterprise 4 4 on laptop acer aspire 4736, and all hadware I am not detected comprise wifi card and lan card. how detects my hadware that? one again of making ad-hoc at ubuntu 7.10
My landlord upstairs just got a new modem and WiFi by Clear.com and when trying to get the WiFi to work...it just wouldn't connect with my laptop. They have 2 computers upstairs, one laptop and one desktop that recognized the WiFi and don't have any trouble using it. Wondering if there is something I have accidently clicked or changed to make it not connect. It does not have an error message, it just does not connect completely.
i use a HP Pavilion dv6-3016ax everything works perfectly and i am very happy with ubuntu! If i could get the Brightness keys to work and the microphone i'd be even better. The brightness FN keys change the slider but make no physical difference of the brightness. And the microphone just doesn't work.
I've got my xubuntu 10.10 install just about perfect on a little acer aspire d250, apart from a small sound useability issue: In the interests of simplicity and resource usage I removed pulseaudio. After a bit of fiddling I got it so that my USB soundcard (ProDac) is recognized and automatically set as the default soundcard when plugged in. Any sound applications automatically use the USB sound if it present, no need to around with pulse. The only problem is that my netbook's volume control keys still only control the master volume of the inbuilt soundcard, and have no effect on the usb sound. Does anyone know of a way to change which sound device these keys actually effect? I'd like to write a little script so that when the usb device is detected the keys are remapped.
Fresh install Ubuntu 10.10 on Acer Aspire 5050 with new hard drive. I struggled to turn the Wifi's button turn on but led light always on. It does not detect wifi driver. I installed ndiswrapper to get Acer's Winxp driver: netathr.inf by Windows Wireless Drivers from Ubuntu Software download. It's same thing as ndiswrapper.
I'm using netbook Acer Aspire One D250-0Bb pre-installed Windows XP. Now i have Gentoo. I have trouble with Xfce (lastest stable version) , where my keyboard don't react. I can move just with touchpad. I think, it's in X-server driver, but i can't find any information about that.
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 can't get my wireless card to work. I downloaded a broadcom driver for it and i do believe its the right one, but its not helped. I'm running mint 8. The information on my internal wireless card i got using the terminal is:
lspci 00:00.0 Host bridge: Silicon Integrated Systems [SiS] 760/M760 Host (rev 03) 00:01.0 PCI bridge: Silicon Integrated Systems [SiS] SG86C202 00:02.0 ISA bridge: Silicon Integrated Systems [SiS] SiS963 [MuTIOL Media IO] (rev 25) 00:02.1 SMBus: Silicon Integrated Systems [SiS] SiS961/2 SMBus Controller 00:02.5 IDE interface: Silicon Integrated Systems [SiS] 5513 [IDE] [Code]....
I've just worked out how to get the wireless card working with an Acer Aspire D260 wireless card to work. Enter terminal command; sudo apt-get install wifi-radar
Then reboot ubuntu 10.04 after it has installed, network manager should now detect wireless networks in range and allow connection, right click network manager icon and select "Enable Wireless" or "Disable wireless" as required to turn on or off. So many others have had problems getting the wifi to work with Acer Aspire D260 netbooks and ubuntu 10.04.
