Talk:Problem with video output switching

Thitha:

__TOC__
I have found a solution for switching back to LCD with the Intel Cards on my X40. But it semms a bit strange to me so maybe someone can confirm that it also works on other Thinkpads (mine is a X41) and setups before I edit that wiki entry.

If i do echo lcd_enable,crt_disable > /proc/acpi/ibm/video after enabling crt i get to see the screen on both lcd and crt although scrambled on crt. After executing it the second time i get lcd only. So for now i always execute that command twice.

==Describe the problem (cloning) ==
Hello

I suggest to describe the problem a little more in detail. Moreover, cloning, that is to have the display on both screens the external and the LCD, is possible.

Thats interresting. The person that wrote that "lcd_enable" should write which model he has, because I have no problems with my T43.
I mainly use "video_switch".

== X60(s)? ==
Does the problem of switching videao output also exist for the X60(s) series?

Thitha:

Is it possible to connect a beamer (or external monitor) to the notebook, while the notebook is running, and then switch the output from the internal TFT to the external beamer or monitor using FN-F7 or by other means?

----

Any information about whether this chip supports DRI/hardware-accelerated GLX with free drivers or not?

Cheers :)

you need to install i810 driver from xorg7 version 1.5 or above. glxgears shows something around 600FPS. currently you can get from xorg cvs version 1.6 and get 1000FPS.

cheers

=== ATI Mobility Radeon 7000 ===
This is an ATI video adapter

=== Features ===
* Chipset: ATI M6
* PCI ID: 1002:4c59
* AGP 4X
* 8 or 16MB DDR-SDRAM video memory
* External VGA up to: 2048x1536x16.7M at 75Hz

=== Also known (in IBM literature) as.... ===
* ATI Mobility RADEON
* ATI Rage Mobility RADEON M6
* ATI Rage Mobility RADEON M6MC
* ATI Mobility RADEON M6C (eg. M6C-16h)

=== Linux driver - OpenSource ===
This adapter is supported by recent versions of the 'radeon' driver as found in X.Org and XFree86.
==== ThinkPad LCD ====
Display on the internal LCD works as long as you set the monitor settings correct.

For Xinerama to work properly on Fedora Core 4 you need to first configure it with the display tools, then manually add
*Option "MergedFB" "True"
*Option "MonitorLayout" "LVDS, CRT"
to the Videocard0 section.

==== External VGA port ====
Works fine with xorg radeon driver.

==== SVideo port ====
SVideo out is supported by the ati.2 driver from the [http://gatos.sourceforge.net/ GATOS project].<br/>
Read [[How to get TV-Out working on ATI graphic cards|here]] how to set it up.

=== Linux driver - Proprietary ===
This chip is not supported by the proprietary ATI driver

=== Linux kernel Framebuffer driver ===
* tested and working fine under gentoo
* tested and working under debian (with re-compiled kernel 2.6.16-9)

=== ThinkPads this chip may be found in ===
* {{A30}}, {{A30p}}
* {{R32}}
* {{R40}}
* {{X22}}, {{X23}}, {{X24}}
* {{X31}}, {{X32}}

=== Problems (and Solutions) ===
==== Problem with video output switching ====
On some models there are [[Problem with video output switching|problems with video output switching]] and the xorg radeon driver.

==== Xorg & OpenGL ====

See http://forums.gentoo.org/viewtopic-t-451151-highlight-.html for information on how to enable stable OpenGL support. Some of the tricks are:

:* disable the console frame buffer.
:* disable the hardware cursor in Xorg.
:* plus some more.

Additional site: https://stier.is-a-geek.com/~moinmoin/MarksWiki/LinuxRadeonM6LY/Conf1

NOTE: I ([[User:msoos]]) actually got DRI direct rendering with framebuffer and hardware cursor, without ''any'' fancy setting at all (apart from re-compiling the 2.6.16-9 with some more-or-less standard setting) on Debian testing.

Problem with video output switching

2006-03-21T07:59:35Z

Thitha: X23 affected as well

==Affected Models==
*ThinkPad {{T40}}, {{T40p}}, {{T41}}, {{T41p}}, {{T42}}, {{T42p}}, {{T43}}, {{T43p}}
*ThinkPad {{X23}}, {{X41}}

==Problem Description==
===Problems with Intel chipsets===
Disabling the internal LCD (e.g. when using an external Monitor) doesn't seem to work reliably.

* i810switch doesn't have any effect. After disabling the LCD it is still on (but the status display of i810switch claims that is is switched off).

* i855crt doesn't seem to allow to change the state of the internal LCD.

* With [[ibm-acpi]], {{cmdroot|echo lcd_disable >/proc/acpi/ibm/video}} works, but {{cmdroot|echo lcd_enable >/proc/acpi/ibm/video}} doesn't work - so one can't enable it anymore after disabling it. (the strange thing is that when switching to a console with {{key|ctrl}}{{key|alt}}{{key|F1}} the LCD display is used for it, so there must be some way to enable it but I can't find out how to control this in X). I've tried this with version 0.8 and version 0.11 of [[ibm-acpi]].

===Problems with ATI chipsets===
*It is a [http://bugs.freedesktop.org/show_bug.cgi?id=2000 known issue] of xorgs radeon driver that {{key|Fn}}{{key|F7}} doesn't work.

None (yet).
