Thanks for the reply. Clean install from 32 bit DVD. The machine is a HP clarion 2g with 1.5g memory and about 6 yrs old. Nop special graphics card, just stock. It ran 11.2 for over a year just fine. Maybe I got a bad DVD burn. I re-downloaded the DVD ISO and will re-burn. It could be a bad burn, however it checked fine and the MDs were correct. I had this happen once before with 11.1.
If that doesn’t solve it, then we will also need to know the vendor and type of your graphics card/chip and which 11.3 graphics driver is installed/loaded.
In order to help you better, it would make it easier if you could be more specific. 1.5GB RAM is good to know about, but I have NO idea as to what cpu nor what speed cpu is in an HP clarion 2g. I’ve never heard of a “nop special” graphics card. Is this a nVidia? and ATI ? … if so, EXACTLY which make? Which graphic driver are you using?
Maybe ‘top’ (in a terminal) will give you a more reliable idea on what is hogging your resources. Also try ‘iotop’ in case the slow performance is caused by disk-writings.
