Thank you for the answers.
I had to install lshw from the internet (by default Kpackage does not know about it).
Both lshw and lspci say Silicon Integrated Systems [SiS] 661/741/760 PCI/AGP or 662/761Gx PCIE VGA Display Adapter and indeed I want to enable DRI on my X desktop. Do you know where should I look for a driver ?
I have seen no DRI settings (commented or not) in my /etc/X11/xorg.conf file but when starting X server I do get these messages:
(WW) VESA(0): Failed to setup write-combining range (0xc3f80000-0x7000000)
(WW) VESA(0): Failed to setup write-combining range (0xc3f00000-0xf000000)
(WW) VESA(0): Failed to setup write-combining range (...
Anyone knows how should I fix that ?
