</span>I've run across many Optiplex models over the years, but the GX50 predates<br>
them all. Looking up in Google it appears to be a Pentium III. Most PCs using<br>
those predate Intel onboard graphics, among which my GX200 (but not my GX150<br>
or GX110). If your GX50 has the 810E chipset, the Intel driver has in recent<br>
years had limited functionality and marginal performance in Linux. My GX110<br>
has 810E. I haven't powered it up in over 7 months. It's painfully slow. I<br>
don't remember if X even works in it any more. If you really think a machine<br>
nearly 2 decades old with maximum RAM population of 0.5GB warrants refurb, I<br>
suggest you find and install in it an ATI or NVidia PCI gfxcard. The OS and X<br>
need the shared RAM the 810E video is now using.<br></blockquote><div>I'll recycle the GX50s.<br> <br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
The 7600 has 945G video. I have various recent distro installations (among<br>
which Kubuntu 14.04 and above) scattered among various machines using 945G<br>
experiencing none of the trouble your bugs describe, so maybe its problem is<br>
RAM or memory controller. Have you inspected its innards for exploding or<br>
leaky electrolytic capacitors? <a href="http://en.wikipedia.org/wiki/Capacitor_plague" rel="noreferrer" target="_blank">http://en.wikipedia.org/wiki/Capacitor_plague</a><br>
If it has any large uF (680 or higher) OST brand caps that appear normal they<br>
may nevertheless be bad and are worth checking or replacing if you believe<br>
the machine otherwise worth salvaging.<br></blockquote><div>I'll put the dc7600 to one side.<br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
Nomodeset is a workaround that blocks use of Intel driver which causes use of<br>
a low perfomance, limited function fallback driver that will use only modes<br>
provided by the machine's video BIOS.<br></blockquote>OK.<br></div><br clear="all"></div><div class="gmail_extra">Thanks to everyone for their help.<br><br><br></div><div class="gmail_extra">Ian<br><br></div><div class="gmail_extra">-- <br><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div>-- ACCU - Professionalism in programming - <a href="http://www.accu.org" target="_blank">http://www.accu.org</a><br></div>-- My writing - <a href="https://sites.google.com/site/ianbruntlett/" target="_blank">https://sites.google.com/site/ianbruntlett/</a><br><div>-- Free Software page - <a href="https://sites.google.com/site/ianbruntlett/home/free-software" target="_blank">https://sites.google.com/site/ianbruntlett/home/free-software</a><br></div><br> </div></div></div></div></div></div></div>
