After installing both Ubuntu Gutsy amd64 then trying Kubuntu amd64 Gutsy on my Acer Aspire 7520-5115 And having no success with getting the Nvidia interface to work properly, I have solved the problem. Acer Specs : AMD Turion 64 X2 mobile technology TL-58 / 1.6 GHz Display 17" TFT active matrix 1440 x 900 ( WXGA+ ) 24-bit (16.7 million colors) 24-bit CrystalBrite NVIDIA GeForce 7000M / nForce 610M NVIDIA GeForce Go 7000M 256MB Solution: Installed Paldo Linux - It installed flawless and I get 1440x900 resolution. The best I got with Ubuntu was 640x480 and it looked terrible. Unfortunately I still cannot get the integrated camera or wireless to work. I guess Linux in general is just not able to deal with these drivers yet. Camera Acer Orbi-cam (m560x driver), Wireless Atheros 5006/7 Wifi Card AT LEAST I can See with extreme clarity and detail my 17" LCD. And can work in the Linux environment instead of Microstuffed. I did try everything I could find to get the Nvidia interface to work in Ubuntu but it just does not work well enough to take advantage of the higher resolutions. I would like someday to return to Ubuntu I think it is wonderful, but not quite ready for todays less expensive laptops. -- " The fundamental principle here is that the justification for a physical concept lies exclusively in its clear an unambiguous relation to the facts it can be experienced" AE
