I installed Mageia5 on a desktop and at that time I choose not to remove un-needed hardware support files. The installation went well but later the system gave display problems. The display would disappear and be replaced by multicolored horizontal lines somewhat like this: http://cdn.avsforum.com/3/38/380a9be6_v ... 98998.jpeg
I had to reinstall and this time I chose to remove un-needed hardware support files and the system is working well. I am not sure of others have also found similar problem. I would personally like to have all hardware support files so that if I install some other hardware at a later date on this system, I would want it to work immediately.
