I will say that on my old Thinkpad, to use multiple monitors at all, I have to drop all the screens down to 16-bit colour. (Either 65,535 or 32,768 colours, it makes no real difference. Most "16-bit colour" modes are actually 15-bit colour: 5 bits for R, G & B.) On Windows I have to do this manually, by setting both screens, individually, to 32K colours - *then* changing resolutions. The Thinkpad only has 16MB of video RAM, which limits it to 2 screens at 1024*768 in 24-bit colour. In 16-bit colour, I can run 1024*768 + 1280*1024. On Ubuntu, there is no UI for changing colour depth, so I use the xorg.conf file I documented in my blog. You might want to try this if your machine is of a similar age. There are no proprietary ATI drivers for my "Mobility Radeon" chipset - it's too old. -- Liam Proven • Info & profile: http://www.google.com/profiles/lproven Email: lpro...@cix.co.uk • GMail/GoogleTalk/Orkut: lpro...@gmail.com Tel: +44 20-8685-0498 • Cell: +44 7939-087884 • Fax: + 44 870-9151419 AIM/Yahoo/Skype: liamproven • MSN: lpro...@hotmail.com • ICQ: 73187508 -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/
