Glad to hear that Lazarus is working for you, but it doesn't really help me as it's not very usable for me...

Can't find the link to the Lazarus forums where I debated about this, but the problem is that I've tried it with four different Linux distros on four different hardware setups and I still get the same result. Someone suggested that it might be because I only use laptops, and it has something to do with the powersaving setup. What's strange is that it's only Lazarus that's causing this. When running Lazarus in the background with an empty project open it uses 70-80% CPU, when I rescan sources the CPU usage goes down to less then 1% when idling, but increases over time and after a few minutes it's up at 70-80% again. Posted a few traces (strace lazarus-ide) on there but I've heard nothing about it since.
