General Discussion / Chinese Chips
« on: January 30, 2021, 03:36:58 pm »
Hi Folks,

I'm thinking of upgrading my old Aspire 5710 by installing a faster CPU.  Currently sporting a Core 2 Duo T5500, it would speed up, it appears, by about 30% if I could find a reasonably cheap T7600, say, or to be a little less ambitious, a TT7400.  I'm wondering, does anybody here know anything about those chinese manufactured CPUs available on the internet. Are they the real thing?/reliable?/worth considering?  These old processors are no longer made by Intel apparently, so the only other choice would be a second-hand one.  Both routes clearly come with attached risks, but which would be the best bet?  Another issue might be the BIOS.  Would that need to be changed before changing the CPU?  I'd certainly be happier if the answer to that question was a resounding NO!  :)  Anyone out there got an opinion?/information?/advice? (even if it's just 'get a faster computer'. Thanks for reading this anyway,

Best Regards,

Jeff C.

General Discussion / Re: Recent update to V20 - Ulyana

Hi Keith,

Many thanks for the kind words and encouragement. Yes, my recent explorations appear to confirm that Timeshift is indeed part of Ulyana. This makes me reluctant to try removing it. I've made some progress, however, as the app allows me to edit the /timeshift file contents. Consequently I've been able to free up some disk space. I can also modify the frequency of the snapshots that it makes, but I can't seem to prevent it altogether from making more of them. It's making incremental copies so, after the first one, which is HUGE, the subsequent others are relatively small. I find I can also direct Timeshift to store its files on a separate USB stick, rather than on the hard drive, so for the time being I'm going to go out and buy one of those, a big one.
Timeshift is making log files too. I wonder, can I simply delete them? Are they of any use if their associated Timeshift snapshots have been deleted? What do you think? Thank you, by the way, for your suggestion regarding 'The Command Line'. I'll be looking for a hard copy of it if they're available, although the download will be useful in getting me started I'm sure.

Best Regards,

Jeff C.

Hi Keith,
    Many thanks for the quick response. I'm afraid I can't say whether or not Timeshift came as part of the original package. I remember I got a bit excited when I first changed to the Linux operating system and simply went after everything (as noobs do). I infer from what you're saying that I might not need Timeshift at all since it appears that the OS is doing the same thing and saving the result in /var. I can see here that I should study the Linux manual a bit more as I don't yet know enough of the basic terminal mode commands to investigate (let alone manipulate) the hard drive contents. It looks very DOS-like, but I'm sure any resemblance pretty much stops right there and it's donkey's years since I last played with DOS anyway - those were the days weren't they?. I'm wondering, does Ulyana enable me to control the frequency of snapshots being taken? But, hey, I can deal with that once I've cleared some disk space, so, first things first, I'll be taking a look at the websites you directed me towards and pressing on from there. Thanks for restoring my sense of direction.

Best Regards,

Jeff C.

General Discussion / Recent update to V20 - Ulyana
« on: August 03, 2020, 04:40:39 pm »
Hi Folks,
    I have an old Acer 5710 Aspire which I recently converted to Linux v19 Tricia from Vista. I was so encouraged by the change over that I didn't think twice
    before I updated it to Ulyana.
    Following the update the  Acer hard drive has suddenly got very little space left and (consequently, I believe) the machine is running v.e.e.ery slowly. Two
    of the files,' /timeshift' and '/var', have got very big indeed  -  31.1Gb and 28.2Gb respectively. The hard drive capacity is only 70.7Gb anyway, so the
    limited free space left seems to be the problem. My questions are   1)  Why have these files got so big?
                                                                                                     2)  Do they need to be that size?     
                                                                                                     3)  What can I do to reduce them?
                                                                                                     4)  How do I prevent them from getting bigger?
Hope you can still help me out, folks.

Best Regards to you all,

Jeff C.

Hi Folks,

Well, I grasped the nettle and re-formatted the Acer hard drive. Windoze Vista now disappeared, gone forever. Then I went through the Linux loading procedure again and  - Bingo - its all Linux now. With oodles of free disk-space, fast running apps, all that stuff that was promised. Brill. So here I am saying to everyone that helped out a great big THANK YOU! Without your friendly assistance and encouragement I would not have attempted this transition and the improvement in performance is remarkable. I've now tried running Zoom under Linux and it works really well with little or no latency. With my Windows10 machine (which has 4x as many cores as the Acer and runs at twice the speed) the latency interferes significantly with any attempt at simultaneous performance. Jamming sessions with my guitar buddies are definitely out. Its really only good for 'show and tell' sessions on that machine. A complete contrast when compared with this little old Linux machine. I am SO pleased. Gentlemen, I salute you.

Now my learning curve must really start 'cos I still need to set up things like e-mail servers, contact lists. internet favorites etc., so I'll be back with more questions I'm sure. Linux is opening new horizons for me faster than I can think. Thank you all of you once more.........

Best Regards,

Jeff C.

Hi Folks,

So here's the thing. I've now got Mint 19.3 Tricia working on the Acer (from a USB stick). Currently I can boot the machine into Windoze, or into Linux via UNetbootin, using the F2 key at start-up. I guess this means it's still an unexpanded file on the hard drive. Once its up and running in Linux I've tried using the Install Linux icon from the menu at the side of the screen. This gets me as far as the partitioning page but neither of the available choices displayed is selectable. Neither box will let itself be ticked. I suspect that this is due to the limited hard drive space available. I believe the hard drive started out with 80Gb. I got rid of as much stuff form it as possible and managed to increase the available free-space from 19.5Gb to 25.5Gb. I think there still might not be enough room for the installation to happen so I'm thinking about removing the original OS completely (it is useless now, isn't it?). Never done that before, though, and not sure how to proceed. Or should I re-format the drive? Never done that before either. Additionally, will the fact that the original OS was 32-bit and the Linux OS is going to be 64-bit have any bearing on all this, particularly in relation to the current formatting of the hard drive. I don't know enough about file formatting....

I'm liking very much how Linux works, by the way, and the Mint GUI is very friendly towards old Windows users. And yes. it seems to work quicker too. Most encouraging. I'm also developing a plan 'B'. I bought a bootable CDRom from  E-bay. It was extraordinarily cheap and the postage was free. It hasn't arrived yet and I don't know when it might, due to the current national crisis, though I'm not fretting too much about this at present- no great loss, really, if it doesn't arrive and E-bay sellers take assiduous care of their reputations. It may come in handy....


Hoping I can get some more advice, please.

Best Regards to everyone,

Jeff C.

Hi Folks,
Phew! What an encouraging response and warm welcome! Thank you so much! It's really gratifying to see the level of interest and support available. I have a number of questions that came out of the replies I got.

@David - Is there any technical reason I should stay with a 32-bit operating system when it seems the CPU will handle a much higher 64-bit resolution?

@Rich - I should like to be able to run conferencing software (as in "Zoom"), record the conference sessions occasionally (I'm a member of a couple of U3A guitar workgroups) and possibly run a music transcription program like "Guitar Pro" or similar. Or am I being too ambitious with this machine?

@Keith - Moderator, I salute you. I'm thinking that maybe dipping a toe in the water would be the best way to start this adventure. Gives me the option of getting back to square one without too much hassle. So some advice on preparing a "Live USB", and on how to 'boot' from it would be most welcome. As well  a steer on which Linux version might be the best choice bearing in mind what I would like the machine to do.

Here's a thought - if it weren't for Covid-19 I wouldn't be doing this. Just goes to show that some good can come out of the very worst events doesn't it?

Hope I'm not being an over-demanding idiot...…

Best regards and thank you to you all,

Jeff C.

Hardware Compatibility / Isthis possible

Hi folks,
    I have an old laptop running Windows Vista. It doesn't want to connect to the internet any more and the (obscenity deleted) operating system won't connect to the M'soft update centre. probably, it's not there any more for Vista. So, I'm wondering if I can change the operating system to Linux, and still use this device as my Zoom communication centre?
Technical Spec. as follows:-         ACER Aspire 5710 laptop
                                                 Intel 2-core CPU   T5500   1.67GHz
                                                 2.00GB Ram
                                                 Running activated Vista Home Premium 32-bit operating system

It seems a pity if I can't extend the usefulness of this very trusty machine, which has served me well since I got it.
Can this machine be converted? If so, anybody out there with some good 'How-To' advice?

Best Regards and Happy Isolation

Jeff C.
