Hi Guys,
I'm new to the forums so if this question is in the wrong section please let me know.
I have tried installing both Ubuntu 12.04 and CentOS 6.3 (both 64bit) on a PowerEdge 1850 with 16Gb of RAM and both installations went well apart from the fact that every 12 seconds or so the screen flickers (LCD monitor). I have tried various LCD monitors with the same result. I hasten to add that these two distros were separate installations and not installed at the same time !
Initially I though it may have been the screen refresh rate but when I changed it to 75Hz I lost the display alltogether. I'm a newbie when it comes to Linux installations so perhaps I'm missing something obvious. The screen flicker doesn't happen under Windows 7 which I installed to see if the problem remained.
Server specs as follows...
PE1850
2 x 3.4GHz CPU's
16Gb RAM
2 x 73Gb HDD's
Any help greatly appreciated.
Graham
