My first real issue is I have an external USB 500GB hd that I'm trying to transfer files to over my home network. The files transfer, but at pretty low speeds. It seems to write at maybe several megs a second for about 2-3 seconds and then it hangs for 20 or 30 seconds. The file system on the external drive is ext4 if that makes any difference. CPU usage is also pretty much pegged. I've attached a screenshot showing some info. The next problem is if I leave the computer alone for several hours, I can't bring it back up - screen doesn't wake back up. It shouldn't be sleeping since I set it to never sleep in the power management "control panel". I suspect this issue may be related to the graphics card (pci Radeon 7000) since sometimes I can get the monitor to wake back up but the screen is purplish and has Ubuntu repeated across the screen (clearly incorrectly) and the mouse cursor is a mostly white box full of pixels of various colors. I didn't see any video drivers in the software update thing, and thats about the extent of my knowledge with drivers in linux. Computer Specs: Some Intel motherboard Celeron 2.4Ghz 512 Megs of RAM PCI Radeon 7000 gfx card Edit: Don't know if this helps or not, but the board does not have onboard LAN, so I'm running a PCI network card. But at this time I don't remember what card it is, I can remove it and look if necessary (or if there is some way to tell what it is within ubuntu...) Edit2: I guess no screenshot, I can't seem to get that to work. I'm not getting asked where to save the screenshot too, nor is it going to the clipboard (or maybe it is, but I can't get it to paste into OpenOffice Draw). Edit3: Managed to get a screenshot finally. Didn't do anything different, but I guess since the CPU wasn't pegged maybe that helped? Something is definitely not right with the system. As you can see CPU is not pegged now, and seems like normal load for a LAN transfer, perhaps a bit high.. But the system really feels like its under full load, it is incredibly sluggish. Firefox (and other open windows) often dim, which I'm guessing is like when windows go whitish in Win 7 when they become unresponsive.
