Unfortunately there is no simple option to disable the HWCursor in xorg.conf for Intel, probably should add one, but if you want to experiment you can try diff --git a/src/sna/sna_display.c b/src/sna/sna_display.c index 965c35c..d1102fe 100644 --- a/src/sna/sna_display.c +++ b/src/sna/sna_display.c @@ -5698,6 +5698,8 @@ sna_cursor_pre_init(struct sna *sna) if (sna->mode.num_real_crtc == 0) return; + return; + #define LOCAL_IOCTL_GET_CAP DRM_IOWR(0x0c, struct local_get_cap) #define DRM_CAP_CURSOR_WIDTH 8 #define DRM_CAP_CURSOR_HEIGHT 9 or diff --git a/src/sna/sna_display.c b/src/sna/sna_display.c index 965c35c..3c373bc 100644 --- a/src/sna/sna_display.c +++ b/src/sna/sna_display.c @@ -5705,6 +5705,7 @@ sna_cursor_pre_init(struct sna *sna) #define I915_PARAM_HAS_COHERENT_PHYS_GTT 29 sna->cursor.max_size = 64; + return; cap.value = 0; cap.name = DRM_CAP_CURSOR_WIDTH; the first disables the HW cursor entirely, the second disables cursor resizing.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
