Greetings guys. In first place, I want to say a great «thanks!» to you all. Your work at the field of X programming and creation of the perfect & stable video drivers is really outstanding! But, unfortunately, a little occasion with video has been observing on my laptop. The cover story: Recently, I forced my Dell Inspiron 1501n up with a new LinuxMint_x86_x64 release as well as x86-free-radeon driver. Before this migration, I used PCLinuxOS which have x86_32 support and Ati proprietary driver also included. My laptop, mentioned above, contains Turion MK-36 (x86_64), 1 Gb of Ram & Xpress 200M IGP. I didn't make much attention of free ram available before, but due to switching to x86_64 I had to. Certainly, the performance raised up, but the system free memory became an extremely low (I expected a variety of decrementation, but not in so terrifying amount). Therefore, I tried to change the situation by lowering a video memory range. By default, there are 256 Mbs of UMA+SidePort memory the system reserves to. This option merely is not presented in BIOS & in the official Catalist Control Center for linux(in my old distributive by the way) is not presented too. I've read a plenty of docs - Xorg mailing list archives, FAQ, all radeon's driver guideline, but the only stuff I have found to play with - is option «VideoRam» / «in Kb» in device section of xorg.conf (and unfortunately it doesn't work). The question: Is there any possibility to minimize a video ram value using x86-free-radeon or for now it's not available?
