I have installed Ubuntu 14.04 LTS in Lenovo Essential G510 laptop after erasing Windows 8 which came pre-installed(after trying Windows 8 and Ubuntu dual boot with hanging problem persisting). The system hangs in below two situations: 1. Watching videos in youtube in fullscreeen mode. 2. Copying files from the shared local area network.
Laptop specification : Intel(R) Core(TM) i5-4200M CPU @ 2.50GHz, 4 GB RAM. Network controller- Qualcomm Atheros AR9485 wireless network adapter(rev 01) Ethernet controller- Qualcomm Atheros QCA8172 Fast Ethernet(rev 10)(subsystem Lenovo device 3801) VGA Compatible controller- Intel Corp 4th gen integrated graphics controller(rev 06).
I switched to ubuntu with lot of expectations but this glitch is bothering me. Please tell the fix..
