I recently installed elementary OS Freya 0.3 on Dell Inspiron duo 1090 Netbook (Intel Atom n550 @1.6GHz Intel NM10 Chipset, GMA3150 Graphics) and my experience with elementary OS is semi-good, why semi? Due to weird graphics issues. The animations are mostly smooth, only changing pages in apps menu isn't smooth at all, very laggy and sluggish, as well as minimizing and maximizing apps/windows. Graphics tend to have minor artifacts when transitioning from login to desktop, and changing workspace (black parts of screen for split-second). I've updated elementary OS with oibaf's repo added, elementary OS updater installed some updates from his repo (VDPAU mostly), and it did no changes whatsoever, maybe window dragging on desktop is a little smoother, but artifacts still happen, can't install Intel Drivers due to "Distro not supported" error, and some people say elementary OS has it's own Freya optimized Intel drivers included, and don't need installing it manually (even so, tried to install anyway, still distro not supported error). My question is simple: What can I do to solve this problem? Is there anything that can help? Looking forward for a response, Cheers!
If you installed before the 3rd of September 2015, then you won't have the new graphics stack included in elementary OS Freya 0.3.1:
At the heart of this upgrade is the latest Hardware Enablement stack from Ubuntu 14.04.3. It includes version 3.19 of the Linux kernel and an updated Mesa that fixes the dreaded “double cursor” glitch. Workspaces in the Multitasking view also now work properly on Nvidia Optimus. The new hardware stack also brings better support for backlights and touchpads on certain laptops, a host of performance and power-related improvements, and support for 5th generation Intel processors. This release should also improve support for (U)EFI systems, especially when installing without an internet connection.
Second to this, GMA graphics are some of the lowest ranked graphics in place, they are probably worse than running on a decent processor, which is another thing you rank fairly low on. While elementary OS is reasonably lightweight, you will experience issues on older/slower hardware. The Dell Inspiron Duo is a 3-star laptop.
