I just spent the last hour trying to do this unsuccessfully. Xorg -configure always fails with "Number of created screens does not match the number of detected devices", which seems to be a known issue. Manually creating the file causes Xorg to fail. All other attempts at modifying the config results in Xorg failing to start. <span style="color: rgb(34, 34, 34); font-family: sans-serif; font-size: 16px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: 24px; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 1; word-spacing: 0px; -webkit-text-stroke-width: 0px; display: inline !important; float: none; background-color: rgb(255, 255, 255);"> <div class="moz-cite-prefix"> On 4/20/16 01:31, Michel Dänzer wrote: </div> <blockquote cite="mid:57173E58.7020603@daenzer.net" type="cite"> <pre wrap="">On 19.04.2016 16:18, J Mo wrote: </pre> <blockquote type="cite"> <pre wrap=""> The other system I put my drive into had a Nvidia GTX 970 and definitely nouveau as it's newly installed Debian as of last week and I made no special configuration changes. </pre> </blockquote> <pre wrap=""> So, can you check whether the Xorg modesetting driver is used with that, and whether it enables glamor acceleration?
