The reason I haven't pushed that <br>> change, yet is because I'd really like to see you guys fix your systems, <br>> first, so we can figure out what's breaking them. So, please don't give <br>> up on fixing them and just settle for the workaround.<br><br>It makes two of us. I am willing to experiment, so if you or any other developer / user have any other suggestions, I'll be willing to try them. I really want to help fix myth work, although it's not myth's problem.<br>> <br>> As I mentioned, your cards should work fine--as a matter of fact the <br>> OpenGL requirements for the MythTV UI are so slight that even a GeForce <br>> 440MX (from 2002) can do a 1920x1080@60Hz UI without breaking a sweat, <br>> so a 10-yrs-newer card shouldn't have any issues. We really need to <br>> figure out what's breaking your system so that we can help others fix <br>> theirs, as this seems to be common to at least OpenSuSE, and possibly Arch.<br>> <br>> Mike<br><br><br>Thanks again, <br><br>Yianni.<br></div> </div></body>
