DebianOn is an effort to document how to install, configure and use Debian on some specific hardware. Therefore potential buyers would know if that hardware is supported and owners would know how get the best out of that hardware. The purpose is not to duplicate the Debian Official Documentation, but to document how to install Debian on some specific hardware. |

Kernel
kacpid bug
There is a bug where the kernel's kacpid thread uses almost 100% of a single CPU core. The fix is to add this to /etc/rc.local:
echo disable > /sys/firmware/acpi/interrupts/gpe01
Note that this bug only happened once I installed the Nvidia X.org video driver.
More details here:

Display
Laptop has an nVidia Corporation GT216 [NVS 5100M] video chip. The Nouveau X.org driver works fine with one exception. Suspend/hibernate do not work with the nouveau x.org driver which is the default driver for new installs
Using the proprietary Nvidia drivers will allow the system to suspend/hibernate and resume successfully. To install:
- Install nvidia-kernel-dkms and all of its dependencies
- Back up your current xorg.cong
Replace your current xorg.conf with:
- Reboot
Audio
Crackly sound at reboot or shutdown. Suspect that audio output from chip to amp is not being put in an high impedance state when the drivers are being disabled.
Keyboard hotkeys
'?QuickLook 3 button with LED indicator' :
'?QuickWeb button with LED indicator' -
'Wireless on/off button with LED indicator' -
'Touchpad on/off button' -
'Volume mute button with LED indicator' -
'Volume down button with LED indicator' -
'Volume up button with LED indicator' -
'Calculator button' -
Toggling the touchpad on/off button sometimes causes a strange focus problem where the keyboard presses are not going to the window on top. The only fix is to switch to the console and back. Only happens the first time the button is pressed in a login session.
I suspect that the touchpad button is related to the general problems with the pointing devices covered in the next section.

Power Management
Hibernation fails miserably using the Nouveau X.org driver.
Installing the Nvidia driver will allow the system to sleep and wake up but most of the time it wakes with a black screen. Switching to the virtual terminal (CTRL-ALT-Fx) that has X.org running will get you back to the desktop.
The /var/log/pm-suspend.log log showed:
To fix this create /etc/pm/config.d/10no-vt-switch:
Ethernet
Found that it does not work with my low-end gigabit switch( DLink DGS-2208 ). Trouble negotiating a link. First time this has happened with the switch. Unsure if it is a hardware or driver issue.
Windows 7 64-bit Iso
WiFi

Requires non-free drivers and firmware. See: iwlwifi. Install the firmware-iwlwifi package from the non-free repository.
Works fine.

Ambient Light Sensor
This feature which will automtically adjust the screen brighness acording to the amient light level. To turn it on now:
sudo modprobe hp-wmi
echo 1 sudo tee -a /sys/devices/platform/hp-wmi/als
To enable this feature permanently follow these steps:
- Add a line containing 'hp-wmi' to /etc/modules.conf
Add the following line to /etc/rc.local:
lspci
lsusb
lsusb -v grep -E '<(Bus iProduct bDeviceClass bDeviceProtocol)' 2>/dev/null
USB Host controllers entries (without OHCI, UHCI, EHCI) are removed too.
