Deja Ubuntu still Kinda SUcks Again I fry my AMD black edition 965 x4 and motherboard 64 bit.Was content staying with Ubuntu 15.10 since it allowed my obsolete AMD video card to work while subsequent editions didn't. Relegated to my HP mini 1116NR with two MB ram I got the resident XP 32 bit running pretty zippy. But I wanted my Ubuntu back so I went and installed Ubuntu 17 and then 16 but neither of them made running my onboard Broadcom modem possible. I try 15.10 and the modem works flawlessly at installation and thereafter.WTF? Why am I screwing with modems years after that was no longer a problem. Fine. But now Ubuntu 32 bit is slogging along barely working and after digging it appears to be the if you plug in USB stuff IRQ/9-acpi goes nuts on the processor and virtual processor on the N270 Intel chip and takes up %100 of the cpu so nothing works. No apparent work around works shutting off acpi and others so I unplug the USB hub... But still performance sucks. It turns out that COMPIZ is eating to much cpu as well. Support the new desktop and the crappy guess what you want search for applications and other crap menu shit thing that has all thosefilters and tie ins to services...which I ignore and install classic menu instead all the time anyway... So then I install the Xubunt Desktop log out log into it and that goes flawlessly. My machine humble 32 bit mini is able to function fairly well...although consigned to obsolete browsers since my platform is only 32 bit it takes some tweaks to get Firefox and CHromium to perform adequately. So obliged to head back to a small ram 32 bit machine on Ubuntu if you move past 15.10 you are screwed. And old bugs aren't fixed. And Modems start not to work all over again. And Compiz Desktop can't funtion without being a hog on the CPU and who really needs it anyway with that crap guess what you need search menu thing. And systemd or not Ubuntu has gone the wrong way and as a desktop has no backward compatibility and past 15.10 it can't run a broadcom modem in 32 bit. And deja vu all over again it doesn't work out of the box and one is jumping through hoops to make Ubuntu work because the latest versions are for people that have the latest hardware i.e. money and its not desktop software but some sorta everything pseudo phone software that is not even forward compatible with a damn Broadcom modem. So things haven't changed when things that once worked don't anymore.
