I hope that I am putting this information in the right place. I would also like to preface this problem with the statement that ubuntu 8.1 and XP have a similar track record with this problem with me. I have a 2.6.24-23-generic (#1 SMP Thu Nov 27 18:13:46 UTC 2008)Kernal, gnome,quad6600, atiradeon rv250(open source driver), intrepid 8.1 all updates no (compiz or fusion or) desktop effects. I recently bought a new monitor.samsung 2333SW lcd 23". the monitor is not recognized by the capplet (configure display settings). the resolution is not optimal. I do not know how to change the resolution. I have forgoten the comand for my Xorg version and the version does not show up in the sysinfo application. the current resolution is 1024*768 48Khz 60Hz NN. the best resolution is 1920*1080. My situation is improved from the previous monitor but I am hopeful that I will be able to use the better resolution soon. perhaps I will find more information on this issue if I use different search key words but this was the closest I could find. It would be nice to have a few more designated key words(areas or connections in the database) ATI,MONITOR,Nvidia above I noticed that there was a request for some info. I have provided it below. root@eric-desktop:/home/eric# lspci 00:00.0 Host bridge: Intel Corporation 82G33/G31/P35/P31 Express DRAM Controller (rev 02) 00:01.0 PCI bridge: Intel Corporation 82G33/G31/P35/P31 Express PCI Express Root Port (rev 02) 00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01) 00:1c.0 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 1 (rev 01) 00:1c.2 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 3 (rev 01) 00:1d.0 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #1 (rev 01) 00:1d.1 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #2 (rev 01) 00:1d.2 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #3 (rev 01) 00:1d.3 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #4 (rev 01) 00:1d.7 USB Controller: Intel Corporation 82801G (ICH7 Family) USB2 EHCI Controller (rev 01) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1) 00:1f.0 ISA bridge: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge (rev 01) 00:1f.1 IDE interface: Intel Corporation 82801G (ICH7 Family) IDE Controller (rev 01) 00:1f.2 IDE interface: Intel Corporation 82801GB/GR/GH (ICH7 Family) SATA IDE Controller (rev 01) 00:1f.3 SMBus: Intel Corporation 82801G (ICH7 Family) SMBus Controller (rev 01) 03:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8056 PCI-E Gigabit Ethernet Controller (rev 13) 04:03.0 VGA compatible controller: ATI Technologies Inc Radeon RV250 [Mobility FireGL 9000] (rev 01) root@eric-desktop:/home/eric# root@eric-desktop:/home/eric# lspci -vnn 00:00.0 Host bridge [0600]: Intel Corporation 82G33/G31/P35/P31 Express DRAM Controller [8086:29c0] (rev 02) Subsystem: ABIT Computer Corp.
