=== Linux ALSA driver ===
==== Installation on Debian GNU/Linux ====
The AD1981HD installs by default in Debian. To get it to work type 'alsaconf' on the command line as the root user.

{{ cmdroot| alsaconf }}
{{HINT|To become root, type su at the command line.}}
==== Problems ====
* As of kernel 2.6.17, some users report a missing master volume control (e.g., with the T60p and Z60m), as described in this thread: http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg17089.html
: As of ALSA 1.0.13 the master volume has returned. Download the latest modules from your distrobution to fix this problem. Otherwise as a temporary fix add model=hp to the snd-hda-intel module option. This will return the master volume control to your control.
{{HINT|If you use Debian, edit /etc/modprobe.d/sound to change ALSA module options. }}
* If you experience crackling noises, this can be avoided by adding the position_fix=2 optional argument for the module.

* If you have problems recording audio, try selecting "Front Mic" as the capture device.
{{ NOTE | There have been reported problems using arecord while debugging, it's recommended to instead use Audacity. }}

* According to a bug in the BIOS, the modem disables the audio device too. If you are having problems with your soundcard and have disabled your modem, try re-enabling it. On some systems disabling the modem results in fixing some problems, so if you haven't disabled the modem, try it.

Cinix:

= CD/DVD Burning =
I wasn't able to burn CD's or DVD's on my Z60m until I added {{bootparm|libata.atapi_enabled|1}} to my kernel command line. I don't know why or what it does, or if that even really was the fix. If anyone else has this problem and this fixes it, please make note of it. When it wasn't working I received buffer underrun errors.

Problems with ACPI suspend-to-ram

2006-09-02T03:36:11Z

Cinix: /* Troubles on suspend */ Added problems with MMC reader

The following glitches may or may not occur in relation to suspending to RAM:

==Troubles on suspend==
;Permissions:If your suspend is failing, and a {{cmdroot|tail /var/log/acpid}} shows "Permission denied" errors, be sure that your new ACPI event and action scripts have the appropriate permissions.

;Broken sysfs interface:You may experience problems when using {{cmdroot|echo standby > /sys/power/state}} or {{cmdroot|echo mem > /sys/power/state}} (machine goes to sleep and wakes up immediately). This can be avoided by using {{cmdroot|echo -n 3 >/proc/acpi/sleep}} to get it to sleep. This can be also happen if hotplug daemon is still running.

;Hangs on "switching to UP code":You may be using a [[How to make use of Dynamic Frequency Scaling|frequency scaling governor]] such as "conservative" or "ondemand", which sometimes have problems with suspending. Switching to a governor such as "powersave" or "performance" before suspending may solve this problem.

;MySQL daemon running:If you're running MySQL, sleep may also not work, so stop MySQL first, then sleep. Remember to restart MySQL when you wakeup.

;LCD backlight remains on during sleep:When your system is equiped with a Radeon Mobility graphic controller your [[Problem with LCD backlight remaining on during ACPI sleep|LCD backlight may not turn off automatically]]. Use [[radeontool]] to switch off your backlight prior suspend in your sleep action script.

;High power drain during sleep:Also, you might want to take note of the [[Problem with high power drain in ACPI sleep]].

;Built-in MMC reader:If you have an MMC reader, and the computer hangs when attempting suspend then remove sdhci, mmc_block, and mmc_core modules before suspending.

==Troubles on resume==
;Blank display on resume:When resuming from a suspend-to-ram the display might remain black or might only show the pre-suspend output (the system is still rebootable via {{key|ctrl}}{{key|alt}}{{key|del}}). See [[Problem with display remaining black after resume]] for solutions.
;Garbage on text consoles on resume:When resuming from suspend-to-ram the text console displays may show garbage instead of actual text. The machine is otherwise still responsive and X displays fine. If all of this is true, then adding the kernel option '''acpi_sleep=s3_bios,s3_mode''' in your menu.lst or lilo.conf may solve the problem.
;Broken hardware support after resume:
:*The '''serial port''' of the port replicator might not work after resume.
:*The '''parallel port''' might not work after resume. A possible fix is to unload and reload the parallel port drivers: {{cmdroot|rmmod lp parport_pc parport; modprobe lp}}.
:*Problems with the '''CD-RW/DVD drive''' after wake up from ram have been experienced.
:*There is a known Problem regarding '''battery info''' after suspend to RAM. A [http://www.ussg.iu.edu/hypermail/linux/kernel/0511.0/2429.html small patch] exists for kernels 2.6.14/2.6.15.
:*On {{X20}} and {{X21}} (and possibly other) models, the '''sleep LED''' is not reset properly on resume and will keep blinking. If you have the [[ibm-acpi]] kernel module loaded with the <tt>experimental=1</tt> option, you can switch it off on resume by appending the following line to your suspend script:
echo 7 off > /proc/acpi/ibm/led

;Crash on resume:
:*When using '''older ATI proprietary drivers''' a crash on resume can be solved by using [http://freshmeat.net/projects/vbetool/ vbetool]. See the example suspend script [[Problem with display remaining black after resume#Solution for ThinkPads with Intel I830 Chipset]]. This is no longer necessary with recent revisions of the ATI proprietary driver.
:*A crash could also be caused by having '''apic support''' enabled in the kernel config. Try disabling it (in the "Processor type and features" section).
:*On machines with Savage chipsets, the '''savagefb framebuffer driver''' might crash the machine on resume. Make sure it is disabled in your kernel config and use the standard vesafb driver instead.
:*Sonoma chipset based laptops ({{R52}}, {{T43}}, {{T43p}}, {{X41}}, {{X41T}}) utilize the '''SATA layer for disk access''' and SATA does not have power-management support yet. Suspend to RAM crashes these machines on resume. See the [[Problems with SATA and Linux#Hang on resume from suspend to RAM|relevant section]] on the [[Problems with SATA and Linux]] page.
:*When system resumes it hangs right after restarting tasks. This may be fixed by passing ec_intr=0 on kernel cmdline.
;Shutdown on resume:
:If your system immediately begins to shut down right after resume, make sure you don't have acpid running with the power button tied to shutdown. The system is simply sensing the power button event and shutting down. This issue has been reported as a bug against the kernel ACPI subsystem, refer to [http://bugzilla.kernel.org/show_bug.cgi?id=6612 kernel.org bugzilla bug #6612].

;Immediate suspend on resume:
:When running GNOME, sometimes gnome-power-manager will put the system back into suspend immediately after resuming. This is caused by a known bug in HAL that causes some ACPI events to be reported incorrectly after a suspend-to-ram. A simple workaround can be found [http://live.gnome.org/GnomePowerManager/Faq#head-b8b1280115b0a51c2cc27b13a57121130ebf36cb here].
:Note that suspend being triggered by unrelated ACPI events such as disconnecting the AC adapter may also be fixed by the above method.

Cinix: Some configuration and video tips.

=== ATI Mobility Radeon X600 ===
This is a ATI video adapter
=== Features ===
* Chipset: ATI M24
* PCI ID: 1002:3150
* PCI Express x16
* 128MB video memory
</div>
|style="vertical-align:top" |
|}

=== Linux driver ===
2D acceleration is supported by the "radeon" driver in X.org.

==== ThinkPad LCD ====
Display on the internal LCD works as long as you set the monitor settings correct.

==== External VGA port ====
There are known problems. The driver from ATI turns off the switching between internal and external port.
Workaround: Don't use the ATI driver if you want to use this feature - use the VESA driver instead.

For ''Ubuntu Dapper'' read [http://thinkwiki.org/wiki/ATI_Mobility_FireGL_V3200#External_VGA_port single/dual/cloned screen] - should work fine.

==== SVideo port ====
??
==== DVI port ====
??

=== Proprietary ATI driver ===
The [[fglrx]] driver adds 3D acceleration.
==== Configuring ====
Type the following commands after you have loaded the fglrx module:

{{cmdroot|aticonfig --initial}}

{{cmdroot|aticonfig --overlay=opengl}}

{{HINT|To use hardware overlay for video playback, choose an SDL or GL output driver in your video player. This will greatly reduce your CPU usage while watching a movie.}}

=== Linux kernel Framebuffer driver ===
Supported by "radeonfb" for console, but conflicts with X.org when using "radeon" or [[fglrx]].
