Good day all
I'm pretty new to Linux, and was convinced to install it by a friend who swears by it. However, not even he could help me with the issues I'm having.
As per the title, I've got a Radeon 9800-series running Lucid. It's connected to a FullHD LCD using a DVI-to-HDMI cable. Since the PC is used mainly as an HTPC, I would like 1080P resolution, which is lacking at the moment. So here goes a list of questions:
1) The screen setup in Lucid autodetects my monitor as a "Priva Hortimation 37" monitor, even though its not. (Its a Sinotech 47", which is probably a rebranded Chinese generic). I realise it's not the most expensive screen so the screen ID could be wrong, but the issue is Lucid recognises the screen as a 4:3 screen, while it should be 16:9. It gives the highest resolution as 1600x1200 which fills the whole screen, although everything looks squat. If I select 720P, the top and bottom panels are cut off (1080P is not available). Can I try to force linux to see the screen as 16:9, and how?
2) The max resolution is, as above, given as 1600x1200. I've tried using gtf and xrandr (newline, addline, modeline) to manually set up a 1920x1080 resolution, however the newline command returns S-Video as the source. I try to use addline to force DVI, but using that modeline results in a blank display. Is there a way to get gtf/xrandr to automatically allocate a new resolution to the DVI?
3) I've read a lot about ATI-linux drivers, few of them positive. I understand that Lucid installs Catalyst 10.4 as default (correct me if I'm wrong, I'm VERY new to this). However ATI recommends 9.3 for a Radeon 9800. Is it worthwhile going throught the effort of reverting to an older driver? Did it solve a problem for anyone else?
Any help in this regard will be appreciated, I want to use Ubuntu as my sole HTPC OS but so far have not been able to set it up correctly.
Thanks in advance!
