You can use drm-tip for testing, where many of the DRM patches go through. https://cgit.freedesktop.org/drm/drm-tip/ It's fairly up-to-date. I have two systems with AST chips and neither shows any of the symptoms you describe; nor do we have such reports about drivers that use a similar stack (hibmc, bochs). Could you provide the output of dmesg | grep drm Best regards Thomas > > David > > - > Registered Address Lakeside, Bramley Road, Mount Farm, Milton Keynes, MK1 1PT, UK > Registration No: 1397386 (Wales) > -- Thomas Zimmermann Graphics Driver Developer SUSE Software Solutions Germany GmbH Maxfeldstr. 5, 90409 Nürnberg, Germany (HRB 36809, AG Nürnberg) Geschäftsführer: Felix Imendörffer Download attachment "OpenPGP_0x680DC11D530B7A23.asc" of type "application/pgp-keys" (7436 bytes) Download attachment "OpenPGP_signature" of type "application/pgp-signature" (841 bytes)
