<p>Jzxu: </p> <hr /> <div>A new driver has been released on 8 jun 2007.&lt;br&gt;<br /> You need this version 100.14.09 or greater.<br /> ----<br /> Here's the link<br /> [http://www.nvidia.com/object/linux_display_ia32_100.14.09.html]<br /> <br /> == LCD Backlight Brightness Control on T61 ==<br /> <br /> To the best of my knowledge, no one has been able to get lcd backlight brightness control to work with this video card on the {{T61}} when using the proprietary driver. However, brightness control works fine when using the vesa driver, so it seems that the problem lies with the Nvidia driver itself. <br /> <br /> Strangely, 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. This was tested with the acpi video driver included in the vanilla Linux 2.6.21-6 kernel.</div>

<p>Jzxu: Can't change brightness on T61</p> <hr /> <div><br /> == Problem with LCD brightness buttons after suspend-to-ram ==<br /> <br /> On my X60 1706-BM7, it's possible to suspend-to-ram either using s2ram or just &quot;echo mem &gt; /sys/power/state&quot;. There's a problem I've noticed, that after I resumed the machine, the LCD brightness buttons take longer to respond. Symptoms are:<br /> *Before suspending, whenever I press the LCD brightness up/down keys, the screen promptly respond by dimming or brighten up.<br /> *After resuming, whenever I press the same keys again, it takes about 1 sec. for the screen to dim or brighten up.<br /> *After resuming, if I use the command &quot;echo down &gt; /proc/acpi/ibm/brightness&quot; or &quot;echo up &gt; /proc/acpi/ibm/brightness&quot;, the screen will respond right away, just like before suspending.<br /> *Without suspending, using &quot;vbetool post&quot; doesn't give this behaviour.<br /> So I think this problem is related to the buttons itself. Does anyone have a similar experience? Any solutions? --[[User:WilliamPoetra|WilliamPoetra]] 10:55, 25 March 2007 (CST)<br /> <br /> == Can't change brightness on T61 ==<br /> <br /> I'm using a T61 with linux kernel 2.6.21-5 and thinkpad-acpi module v.0.14. For the life of me I can't manage to change the LCD brightness. I've tried using both the thinkpad-acpi method under /proc/acpi/ibm/brightness and also the kernel acpi video method under /proc/acpi/video/VID/LCD0/brightness, but neither works. Nor do the Fn-Home and Fn-End keys work themselves.</div>
