 === LCD Backlight Brightness Control on T61/R61 ===
-There has been an issue with Brightness Control on T61/R61s. This seems to be fixed with the 169.04 BETA drivers from Nvidia. You can find them i.e. here [http://www.nvidia.com/object/linux_display_ia32_169.04.html 169.04 BETA Driver]. You might also need the latest BIOS ([[BIOS_Upgrade_Downloads]] 1.26) as well as the latest version of [[Ibm-acpi]] (thinkpad-acpi, V0.18).

 If the nvidia module is loaded with the argument NVreg_EnableBrightnessControl=1, one can switch to a virtual console, change the lcd brightness level there, and have that level preserved after switching back to the X session. On a {{T61}}, this was tested with the acpi video driver included in the vanilla Linux 2.6.21-6 kernel and on an {{R61}} with {{OpenSUSE}} 10.2.

		+	=== Making Compiz work well ===
		+
		+	Compiz requires a few options to be passed to it, in order to run quickly and reliably. Not using these options can result in anything ranging from general slowness to graphics corruption, depending on the driver version. At the time of writing, the 180.18 beta drivers were used. Below are the relevant parts of a working Compiz startup script:
		+
		+	'''export LIBGL_ALWAYS_INDIRECT=1'''
		+
		+	'''nice --adjustment=-5 compiz ccp --indirect-rendering --loose-binding --sm-disable --replace'''
		+
		+	With these options and the above RegistryDwords, Compiz, videos and OpenGL apps run without any noticable delays or glitches. Note, though, that because of the way X, Compiz, GTK and QT handle memory allocation, window resizing using the 'normal' mode is nigh-on unusable.

		+	=== Disabling automatic power saving ===
		+
		+	The nVidia Quadro NVS 140m, as well as some other newer cards, automatically clock down to save power and stay cool. This can be a nuisance when running a compositing window manager, such as Compiz Fusion - animations will appear to start jerkily, and smoothen out after a second or so once the GPU clocks up. One workaround is to disable automatic power management of the GPU. To do so, add the line
		+
		+	'''options nvidia NVreg_RegistryDwords="PerfLevelSrc=0x2222"'''
		+
		+	to either /etc/modprobe.conf or a (new) file in /etc/modprobe.d
		+
		+	Be warned, that this might cause excessive heat generation and/or premature death of the GPU. It should be safer than overclocking, though.
