I tried on my eMachine 355-M571G251lkk (double core CPU) with 1 G RAM, compared with Mint15 it was slightly faster but as soon as I opened more than one program, it showed obvious memory leak - the mouse cursor frozen or the drop-down menu clicked refused to show menu items apart from a grey box. Basically it is unusable so to speak. During installation, when the installation almost finished, the application frozen at 'copying installation logs'. I forced it to switch off. Is this the reason? I previously used Lubuntu without this problem. Later on I changed to Mint due to though Lubuntu a bit faster, it is apt to annoying problem like missing menu bar while Mint is more reliable and also fast enough.
Mint, LXLE and others does not work on old Thinkpads. Mine is a Thinkpad R50. Tried them "all". "Xubuntu 12.04 is the last of the family shipping with a non-PAE kernel. True, you can hack your way around, but from the official stand point, the vendor does not intend to support ancient processors beyond 2017." (ww.dedoimedo.com/computers/reviving-ten-year-old-laptop-linux.html) Most older distros are removed from downloads, no Xubuntu 12.04 anymore, also no torrent. Anyhow I succeded finding an Ubuntu 8.10 and it WORKS! Took hours to get there, upgrades are now pending.
