Control: tags patch I think I found the problem. It seems to be Fix-a-build-error-with-Xorg-master.patch
To be honest, I don't really understand the patch. According to the comment, instead of just changing one renamed parameter, it changes the calling conventions at the cost of an unnecessary "slight performance drop" in not one but three functions "for consistency" and goes on to explain why it should work which sounds questionable to me and apparently doesn't work after all. So instead doing the simple thing seems to work. I suggest replacing the patch with this one: Index: xserver-xorg-video-qxl-0.1.5+git20200331/src/qxl_option_helpers.c =================================================================== --- xserver-xorg-video-qxl-0.1.5+git20200331.orig/src/qxl_option_helpers.c +++ xserver-xorg-video-qxl-0.1.5+git20200331/src/qxl_option_helpers.c @@ -34,7 +34,7 @@ int get_bool_option(OptionInfoPtr option const char* value = getenv(env_name); if (!value) { - return options[option_index].value.bool; + return options[option_index].value.boolean; } if (strcmp(value, "0") == 0 || strcasecmp(value, "off") == 0 ||
