I'm sorry that you have such a bad experience with it. Please try again with Plasma 5.8 - there is a new design and maybe that is better suited for your GPU. > Just because people don't notice the slowdown on high spec desktops doesn't > mean that it isn't eating up a whole heap of unnecessary watts and affecting > their battery life and/or power bill every time they go to the lock screen. Sorry, but you are jumping to the wrong conclusions here. If you have a GPU, rendering is cheap. That's why one has a GPU and does not do everything on the CPU. The problem here is that your GPU is not well supported and gets emulated on the CPU (sorry Poulsbo was never really supported on Linux and is the odd one. Although being from Intel it doesn't share anything with normal Intel hardware and according to Arch wiki doesn't support OpenGL https://wiki.archlinux.org/index.php/Intel_GMA_500). That is unfortunate for you but doesn't allow to say anything in general as it works just fine if you have a supported GPU. I'm sorry to say but with that hardware you will not have fun with any modern desktop. Be it Plasma, GNOME, Unity, Cinnamon, E18, Elementary, etc. etc. You want a desktop which doesn't use OpenGL - which is nowadays hardly any. Consider maybe a bare openbox setup. Keep away from GTK and Qt based applications, keep away from browsers. They all need OpenGL and you don't want that emulated on the CPU. I'm sorry for you that you picked up the one device which doesn't support Linux. -- You are receiving this mail because: You are watching all bug changes.
