When calling up the Gxine Player and going to File/Configure and then to Re-run setup wizards, click next and a window appears with a list of System configuration checks. They are all green, so Oké, except for the last one, the Check for MIT Xv Extension. That one has a red point, telling us something is missing. In order to know, you click the details button and another window appears, telling us: Health Check Results, video_out_xv: No adaptors found. You can improve performance by installing an X11 driver that supports the Xv protocol extension. In the good old days systems use to propose the missing driver and asked permission to install it. But these were pre-modern days and long gone. So we have to figure out ourselves. Does anyone have an idea?
Before you propose, the package X11-utils cannot be the missing link as I have installed that package already. To give a clue, this problem only appears in Mint and Kubuntu but not in Ubuntu. So what's in Ubuntu that's missing in Mint? The health check talks about missing adaptors as well as a missing driver.
