Debian :: Can't Change Brightness In Debian Lenny
Apr 16, 2010
I installed Debian Lenny on my old IBM thinkpad R40e but i can't change the brightness either with the Fn keys or with the brightness control debian has. i have searched around and it seems to be a problem with linux on IBM thinkpads but i don't know that much about this sort of thing so any help would be appreciated. if you need any more info then just ask.

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've an asuspro (more precisely the p2520la version) notebook with the fn+f5, fn+f6 buttons that should change brightness of the screen. But they don't work. For volume it's ok (fn+f11/f12), and if I go in the system settings I c an change manually the brightness (I use kde so there is a bar with which change it). But when I'm outside and the screen brightness is low I found difficult to find the menu settings and the hardware buttons would be better.I've tried adding to the kernel the "acpi_osi=" command but doesn't work.

I have installed kmilo, modprobed nvram and added line: KERNEL=="nvram", MODE="0666", GROUP="nvram" to 91-permissions.rules. I used command addgroup nvram and add me ( user tomasso ) to nvram group. Kmilo works fine but I am not able to change brightness of my laptop in kpowersave or by using fn key on my laptop keyboard. I am in powerdev group too.

After some experience with ubuntu i have just installed Debian Squeeze on a dell inspiron 1564.
I have faced with some problems:
1- The screen brightness doesn't change. neither the brightness hotkey works nor the brightness applet changes the brightness
2-There is no sound
I had none of these problems with ubuntu lucid.
Here is the output of lspci command:

Well I have installed lenny from netinstall, with Xfce on a virtual machine, everything runs smooth and I really like how does it work, I just have a little big problem, the resolution is too high, it is higher than the host resolution, if I have to work in the down part of the screen I have to scroll down in host, it is kinda annoying, under screen config (right click>configuration>screen config) for resolution only the default option is available. I have googled and I have found that /etc/X11/xorg.conf must be modified to use another resolution, but I'm not sure of what to change or what to do exactly.

i was trying to use gnome and kde but i don't like them. I tried xfce and it seem to fit my needs but.My computer is used to be powered on for a weeks. While time passes, a process xfdesktop begin to use more and more memory and to free RAM i need to log out and log in again.
I tried squeeze yesterday on my virtual machine and it has 4.6 and seem not to have that bug, RAM usage is static(yes it still works when i write this and have memory usage 34492k, which is not changing for an hours of usage already), also 4.6 is MUCH better than 4.4.
i already tried adding squeeze to "sources.list" but i can see too many dependencies which should be upgraded if i install 4.6, i'm beginning to afraid it can crash entire GUI(or entire system, i can see there is libc6 required to be updated).

i do have a strange problem get running php5 on lenny 64 inside apache2. i had installed it as all instructions on the web does: # apt-get install php5 libapache2-mod-php5 php5-cli php5-common php5-cgi
apt has enabled php automatically, so
/etc/apache2/mods-enabled/php5.conf does have inside:
<ifmodule mod_php5.c>
AddType application/x-httpd-php .php .phtml .php3
AddType application/x-httpd-php-source .phps
</ifmodule>

I have added a 10 Mbps network card to my SGI O2 MIPS workstation running Debian Lenny running the 26-2 kernel. The workstation already has an onboard NIC which is working fine.(eth0).
lspci -v shows ths card as:-00:03.0 Ethernet controller: Compex ReadyLink 2000 (rev 0a) Flags: medium devsel, IRQ 18 I/O ports at 1800 [disabled] [size=32] Upon googling I found out that this card is an NE2000 clone. I downloaded the latest 2.6.36 kernel sources and did the following:-
1. Make Menuconfig
2. Loaded an alternate kernel config file (my working kernel config file)
3. In DeviceDrivers->Network device support->Ethernet (10 or 100 Mbit)
I selected ASIX AX88796 as the help associated with this showed it as an NE 2000 clone. configured it to be a module and did make, make_modules and make_install. Edited /etc/Modules to load ax88796 and added an alias eth1 ax88796 to this file. copied the new kernel to the /boot and did a reboot, the machine booted up fine and udev -r showed the 2.6.36 kernel and lsmod showed ax88796 loaded. But, Iam not able to bring up eth1 using:-
ifup eth1
The error messages given are:-
SIOCSIFADDR: No such device
eth1: ERROR while getting interface flags: No such device
SIOCSIFNETMASK: No such device

I'm trying to install Debian/Lenny on a iBook clamshell. I couldn't seem to burn an install CD that the iBook would recognize, so I eventually copied the contents of the CD onto a self-powered USB drive and I can now get the iBook to boot off of that thru open firmware. However, when I get to the Debian installer main menu, it still won't read the CD, and apparently it does not have network drivers to install over Ethernet. Is there any way I can supply a driver for the ethernet interface (lspci reports that its a sun GEM ethernet interface) or somehow convince the installer to install from the content of the USB drive (which is a duplicate of what's on the installer CD)? Heck, if it'd be easier to get the Airport interface running to reach the Internet I'd be up for that too.

Could anyone tell me how to get Debian Lenny to automount CDs the same as Ubuntu does i.e. automatically, with a Desktop icon etc.I've worked out how to automount CDs using autofs, which is OK, but it still doesn't seem quite as good as the way Ubuntu does it.

I have problem with loging, actually iptables logs a data but it seems that for some reasons does not writes in a log file:
Code:
iptables -L -v
Chain INPUT (policy ACCEPT 406 packets, 124K bytes)
pkts bytes target prot opt in out source destination
0 0 ACCEPT tcp -- any any xxxxxxxxxxx anywhere tcp dpt:xxxx
[Code]....
i checked /var/log/message and /var/log/syslog nothing is here related to iptables. then i create separate file for Iptables by adding this: kern.warning /var/log/iptables.log in my rsyslog.conf it does create iptables.log file inside /var/ but its still empty

I've found that I need to use pppoeconf, but it doesn't work. I have default Debian kernel with PPPOE module. After looking for the modem it gives me the following message:"Sorry, I scanned 1 interface, but the Access Concentrator of you provider did not respond. Please check your network and modem cables. Another reason for the scan failure may also another pppoe process which controls the modem."pppoeconf detected the interface successfully (eth0, I have only one interface), but doesn't work. It does, however, work with my router connecting without any issues.

I am curious that if I change the sources list to include "stable" instead of "lenny" (for the Lenny release, for example) will my system upgrade to the Squeeze sources when Debian Squeeze becomes the new stable and Lenny is the oldstable? I'm brand-spanking-new to Debian and I love stability (for my workstation) but I also need a lot of features that are only available with some newer packages. I plan on having to compile a lot of packages from source but I would really like to be able to ignore making changes to my sources list. Will changing "lenny" to "stable" make this work?

My laptop brightness gets set to maximium each boot.
Just wondering if this is the case for other laptop users. I have a Lenovo Thinkpad SL500 (GeForce 9300M GS) and am running Testing.
Ideally I'd like it to remember my last setting (which is usually the lowest). It'd be nice not having to turn it down each time I reboot/power-on.
It actually starts off at a low setting but during the boot process (before gdm and just after the "Waiting for /dev" line I believe) it suddenly gets set to max.

When I first install debian I couldn't change the screen brightness at all not manually nor with function keys, but I tried some of the solutions I found on the internet and now I can change the brightness manually (from the power management or the battery icon) but when I use the function keys it takes them like 2 to 3 minutes to respond and cause the system to hang (even mouse curser not responding) and then I'm forced to manually reboot the system, here is some information :
Code: Select all$ ls /sys/class/backlight/
acpi_video0 intel_backlight
Code: Select all$cat /etc/default/grub
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'
[Code] .....
And I've tried this:
Code: Select allsudo -i kwrite /usr/share/X11/xorg.conf.d/20-intel.conf
And I add the following in this file
Code: Select allSection "Device"
Identifier "card0"
Driver "intel"
Option "Backlight" "intel_backlight"
BusID "PCI:0:2:0"
EndSection

When I logout out of gnome, the brightness reaches maximum level. I've tried adding a script to adjust the directory "/sys/class/backlight/intel_ backlight/ brightness" to the rc.local file. I'm not sure if it has to do with my video card but it certainly could be the case since I'm using an experimental package for the Intel graphics card.

I have an issue with Debian 7.8 (wheezy) on my laptop. I've had to reinstall Debian on my laptop and since then I've had issues getting brightness controls to work properly.
It's a Core i3 370M processor with Ironlake graphics, I've had this issue before with Ubuntu and I sought [URL] ..... I've tried the steps that worked for Ubuntu (thinking they'd be the same as they're both Debian based) and it hasn't worked.
What should I try to get it to work? Since I have updated my grub config (as per the Ubuntu fix), brightness doesn't work at all and my screen now tiles ever so slightly when moving the cursor from side to side. I'll revert those changes if need be or if this issue cannot be resolved.
I've tried to install the Intel graphics drivers from 01.org, however I get an issue with libglib dependencies not being satisfied ( libglib2.0-0(>=2.37.3) ) that how to resolve.
