debian stable - v11 - bullseye - firefox esr performance improvement on old hardware

debian stable - v11 - bullseye - firefox esr performance improvement on old hardware

For some websites, the default settings in firefox esr on my old hardware, seems to make the site slow to load, and have "top" indicate unexpectedly high system load (4+), even though the website was mostly text (news google com).

<alt> => Edit => Settings => Fonts and Colors => Advanced (is a button) => UN-CHECK "allow pages to choose their own fonts, instead of your selections above."

I discovered if you un-check the setting, under Advanced, for fonts, of "allow sites to override...," the pages are faster to load, and the system load is noticeably reduced on my old hardware.

Debian Stable (v11 aka bullseye) installation to a Gateway MX6214 laptop

Debian Stable (v11 aka bullseye) installation to a Gateway MX6214 laptop.

Downloaded the i386 netinst ISO.

From the preexisting Debian10 installation, used brasero to burn the ISO netinst image into a CDROM

Rebooted from the netinst CDROM.

Used a wired connection to install the default installation.

As root, added my primary user to the "sudo" group. Rebooted. Ran "sudo -l" and confirmed primary user able to sudo.

Updated sources.list to include non-free. Then did "sudo apt install firmware-misc-nonfree" Rebooted.

Updated sources.list to include contrib. Then did "sudo apt install firmware-b43-installer" Rebooted

Disconnected wired connection. Configured wi-fi and connected via wi-fi.

Wrote this entry via wi-fi. Done!

Anyone still here?

Haven't been on LiveJournal in a while, but I just popped in to see if anyone else was still getting on here. I recently installed Debian 8 on my ThinkPad R60 and have been really enjoying it. I've been a Debian user since Squeeze.

Google Music Manager, Wheezy, and libc6 - a bit of a pro tip

If you are using Google Music Manager on Wheezy, do NOT install the latest version until it comes down from the Google repository and it can be installed. The latest Google MM requires at least libc6 2.15, and you likely have 2.13 installed. If you really want to run it, you can upgrade to Jessie (which brings in libc6 2.17), but you're probably better off waiting for Google to fix the problem if you don't want to deal with a Testing distribution.

(Note, Jessie is currently using a 3.9 kernel. I can safely say this works pretty well, but you're getting a kernel that's currently in development.)

Debian Stable (v7 aka Wheezy) installatin to a Gateway MX6214 laptop


Debian 7 stable - installing to Gateway MX6214 laptop



I wasted a lot of time trying to use a USB drive of the debian7 netinst ISO image. DO NOT WASTE YOUR TIME. No matter what I tried, the BIOS on the gateway would not recognize the USB drive correctly to boot. Would just say something to the effect of 'no operating system found.'


Instead, used my wife's M$ PC to burn a CDROM of the netinst.

Did some googling, to discover some Linux websites 
referenced using ImgBurn M$ freeware to burn an ISO image.

Downloaded the debian 7 netinst ISO to a USB jump drive.
Copied to desktop on wife's M$ system.

Installed ImgBurn to wife's M$ system.
Told ImgBurn to write IMG file to disc.

Put netinst CDROM into the laptop, and rebooted.
(...a few hrs later...)
Success!

...now I just have to learn my way around
this latest Debian Stable. Whee!


EDIT 2013-05-20



Happy to find that I was able to watch youtube videos without having to manually download any adobe flash driver. It just worked : )



Will need to figure out how to enable the laptop's wifi by finding and installing the correct 'firmware.' Will just need to do some googling and looking through the debian stable package lists, then report the solution back here.


TO GET WIRELESS TO WORK
sudo view /etc/apt/sources.list
add 'contrib', so that the file now shows:

deb http://ftp.us.debian.org/debian/ wheezy main contrib
deb-src http://ftp.us.debian.org/debian/ wheezy main contrib

sudo aptitude install firmware-b43-installer
(had to both turn on the wireless hardware [<Fn> + <F2>]
and reboot for the wifi to then be working)

X11 gui programming - suggestions please

Greets

I am working on a hobbyist project to generate a coded text file based on
user input.

I am using C++, and MVC design pattern(s). Have decided it will be licensed GPL v3.

For the GUI (view the user will interact with) I am researching gtk,
curses, and such, but never have used any of them before on a project.

Hoping my fellow Debian LJers (might x-post to the LJ linux grp, too) might have ideas/suggestions based on your
experience doing GUI programming.

I dont' think I will need to draw graphics or images. At this stage I
expect my GUI would just need to view/display/intake keyboard text.


Btw, I asked my SGVLUGers, and have the following as suggestions so far (in no particular order):

ncurses
qt
gtk + glade
fltk
jx


Thanks 
Robert

Debian repos chocked - a half decent solution

It's been noticed by many complaining of the traffic being chocked that the perpetrators are testing shy, - whenever a testing program that is advertising it's presence is used - the chocking stops.

In the case of Debian Aptosid mirrors i am having problem with, i have bein pinging an unrelated site, just to keep the connection alive.
The last two days i did both updates and upgrades while pinging the actual hubs - the ones i could see through traceroute. What do you know - quite a success. The speed so far keeps quite constant and close to normal.

So, the moral, at this stage, until they scratch their buts again, is - if you notice throttling on file downloads (i can't say anything of uploads, and torrent therefore) - try pinging at the same time the hubs.

By the way, two days later, my post with documentation of the TCP disruptions in the debian community is being "moderated". Way to go. With all the activity on this bustling busy forum, it is akin to showing up with your chips and beer on your favorite abandoned playground to find all those guys (and gals) in nice uniforms wearing latex gloves, with metal detectors and anal probes at hand.
Spread them, now!

Is Sid Debian?

I know Debian community is supposed to be moderated. I would assume for some sort of spam and indecent code monkeys. I have made four posts to Debian community. Every one of them posted immediately.
I am very curious what would make it necessary to moderate the post about an ISP preventing downloading upgrades for one particular Linux distribution. I have seen people posting trace logs before, and domain registration details. Of course i am wondering whether apto sid is so evil, that it has to be stopped by all means, and i am the only ignorant one here. You know, old people tend to worry about such things.
SO, please tell me whether i am using some evil Linux distribution and should stop immediately, before it is too late for me.

Block Verizon Reset packets?

Well, it's official. Verizon DSL is blocking a normal use of all the Aptosid mirrors. In two seconds after connection (apt-get update, upgrade, or install) a flood of TCP RST breaks the connection. The only way i am getting (a very slow) upgrades is by running a continuous ping of some other site at the same time. This seems to reset the connection again and again.
It should be mentioned that i see no such blockage on Ubuntu, Debian or Arch mirrors.
I know that iptables –tcp-flags RST RST -j DROP Is one possible solution.
How can it be applied to apt-get use? Any ideas? I do use sudo for all apt-get commands.
I do hate them throttling videos that disagree with some "official" policies, but can live with that. However blocking a normal use of linux distribution feels like they are looking up my ars from the toilet bowl...

Debian stable net install to a gateway mx6214

Was having trouble installing Debian stable into my wife's Gateway MX6214 laptop. It has a Fujitsu 80Gb harddrive.

Symptoms: would get part way through the 'installing packages' step, then system would go blank screen and seem to be locked up.
Tried many times.

Solution that worked for me:
Changed the default partitioning (suggested by the installer) from 3.3Gb swap and rest to '/', to make the '/' partition about 1/2Gb smaller than the default the installer was going to use, leaving a little free space on the harddrive.

Wrote the changed partition sizes to disk, then did the rest of the install in the normal (default) way.

Writing this post from the newly Debian laptop itself :)

To get wireless to work:
1. update /etc/apt/sources.list to include 'contrib':
deb http://ftp.us.debian.org/debian/ squeeze main contrib

2. sudo aptitude install wireless-tools
3. sudo aptitude install firmware-b43-installer

Then I was able to add my WEP key to the network icon/applet in the upper right corner, and be connected to my home wireless network.
