I use Debian 11 and I have installed the "xserver-xorg-video-openchrome 0.6.0-4" package, which is the latest version of the driver found in the Debian repositories.</span></span></span><br></div><div dir="auto"><br></div><div dir="auto"><span class="" lang="en"><span class="" data-language-for-alternatives="en" data-language-to-translate-into="es" data-phrase-index="0" data-number-of-phrases="1"><span>This driver works perfectly but, when I want to lower or raise the brightness with the command "xrandr --output VGA-1 --brightness <value>", absolutely nothing happens, no error message or anything, the brightness is not change. The strangest thing is that if I install an old version of the driver, like "0.5.0-3", the command works perfectly and I can change the brightness without problems.</span></span></span><br></div><div dir="auto"><br></div><div dir="auto"><span class="" lang="en"><span class="" data-language-for-alternatives="en" data-language-to-translate-into="es" data-phrase-index="0" data-number-of-phrases="1"><span>Why does the driver only change the brightness with version 5 and not with version 6? both versions work perfectly, except that in version 6 I can't change the brightness (and no error message is shown to tell me where the problem could be). Is there any parameter that I can change in version 6 to solve it? perhaps modifying the xorg.conf file? are there other ways to change in brightness without using xrandr? Thanks in advance.</span></span></span><br></div><div dir="auto"><br></div><div dir="auto"><span class="" lang="en"><span class="" data-language-for-alternatives="en" data-language-to-translate-into="es" data-phrase-index="0" data-number-of-phrases="1"><span>Here I leave the output of the "inxi -Gxx" command:</span></span></span><br></div><div dir="auto"><span class="" lang="en"><span class="" data-language-for-alternatives="en" data-language-to-translate-into="es" data-phrase-index="0" data-number-of-phrases="1"><span></span></span></span><br></div><div dir="auto">Graphics:<br></div><div dir="auto"> Device-1: VIA CN896/VN896/P4M900 [Chrome 9 HC]<br></div><div dir="auto"> vendor: Biostar Microtech Intl Corp driver: N/A bus ID: 01:00.0<br></div><div dir="auto"> chip ID: 1106:3371<br></div><div dir="auto"> Display: server: X.Org 1.19.2 driver: loaded: openchrome<br></div><div dir="auto"> unloaded: fbdev,modesetting,vesa resolution: 1280x720~60Hz s-dpi: 96<br></div><div dir="auto"> OpenGL: renderer: llvmpipe (LLVM 11.0.1 128 bits) v: 4.5 Mesa 20.3.5<br></div><div dir="auto"> compat-v: 3.1 direct render: Yes<span class="" lang="en"><span class="" data-language-for-alternatives="en" data-language-to-translate-into="es" data-phrase-index="0" data-number-of-phrases="1"><span></span></span></span></div> </body>
