Hi all. First post and also first try with an arch-based distro after 15 years of Deb/Ubuntu and derivatives - so please be gentle with me
I successfully downloaded the latest KDE iso and installed on a spare PC I keep for playing around and testing new distros. I left everything with the Nouveau defaults until installed and then set up keyboard, language and Nvidia driver for a GT 440 card. Used it for a few days and couldn't fault it. So far so good.
I then decided to install to a spare partition on my main "production" PC. This is when I hit a ■■■■■ wall - the DVD would not even boot to a desktop. Apart from an Nvidia TXi 750 card and a different monitor, both PCs have similar motherboards, CPUs etc. I don't multi-boot either PC (i.e. no Windows worries etc).
So far this is what I have tried:
Booting with the default keyboard, language and free driver option. This gave an unresponsive black screen with no mouse cursor after a lengthy echoing of all green "OKs". I did notice that the first boot entry said something to the effect of: "3.361961 Nouveau fault MMIO read fault ... IBUS".
Booting with the default keyboard, language and non-free driver option. Same result as above except the Nouveau fault did not appear (presumably because it booted for the non-free driver).
Booting with driver=free nomodeset=1 as a substitute for the default of driver=free nouveau.modeset=1 i915.modeset=1 radeon.modeset=1. Not sure whether this command/syntax is correct or not but someone should be able to help me here. Same result as above.
Repeated 3. with driver=non-free modeset=1. Same result.
Swapped the DVI Samsing monitor and the GTX 750 Ti card for the older VGA monitor and GT 440 card from the successful PC. Repeated 1-4 above. Still the same black unresponsive screen in all cases.
That is where I have left it. I am presuming that the DVD is OK - indeed I I tried rebooting the first PC with the disk again and it booted fine. I figure I may have something in the Bios that it doesn't like but not sure how to diagnose that.
Can anyone help pls.
PS - Cannot find an icon/option for pasting code?
