From: Ben Hutchings Subject: qxl: Disable by default Forwarded: not-needed This kernel driver is incompatible with older versions of xserver-xorg-video-qxl, so do not enable it by default. It should be enabled by a modprobe configuration file installed by xserver-xorg-video-qxl in jessie. --- a/drivers/gpu/drm/qxl/qxl_drv.c +++ b/drivers/gpu/drm/qxl/qxl_drv.c @@ -47,7 +47,7 @@ static DEFINE_PCI_DEVICE_TABLE(pciidlist }; MODULE_DEVICE_TABLE(pci, pciidlist); -static int qxl_modeset = -1; +static int qxl_modeset = 0; int qxl_num_crtc = 4; MODULE_PARM_DESC(modeset, "Disable/Enable modesetting");
