the flower that is lost!

The most fragrant flower of the day......

may not find a place in your birthday bouquet!

yet,

WISH YOU A VERY HAPPY BIRTHDAY!

19-septmber-2021

The day strolls and drifts into sleep slowly, unmarked by anything significant.

The monsoonal clouds wept gently sometimes, just like most other days of the season.

Generally, nobody takes a second to gaze upon the weeping clouds, rather the world goes about its business in an extra hurry whenever it rains. 

Moments last for a fleeting few minutes. But..., memories stay fresh forever, either too bitter to swallow or too sweet to forget!

Destinations may be out of sight, yet the road... keeps us reminding of the remaining journey....keeps us pushing forward!

Forward, until the destination is reached!

A 19th September is nothing different in faded memories, but....

missing HDMI audio controller in ubuntu based linux derivatives!

    after flirting with a number of linux distros, i decided to settle on linux-mint, for the very friendly and beautiful customization it offers. just as with many other distros, mint also came with its own set of troubles, though minor ones!

this time around, i did not want to run away from this. mint was just too good to give up so easily! i dug the net for solutions whenever mint threw a problem at me.

the most prominent and glaring trouble one may face immediately after installing mint is, loss of WIFI signal after few minutes of booting. i think, this is a problem cropping up in all ubuntu derivatives!

linux community out there was so kind to point me out to the solution!

simply editing a wifi related "CONFIGURATION FILE" on the linux-SYSTEM-FILES was a simple solution but was hard to sift through during starting.

default wifi-configuration is set to turn the power off after few minutes of staying active. this shall be disabled by changing the relevant entry from "3" to "2".

this reconfiguration of wifi settings disables the wifi from turning off automatically! (laptops!?) once this is done, wifi signal becomes very stable.

we can also ensure, that the wifi power-management is permanently turned off by using command "iwconfig!" this command would show WIFIpowermanagement is turned OFF!

 

next problem that i used to encounter was, HDMI audio controller missing and audio becoming total dumb!

ubuntu based distros make use of an audio-server named PulseAudio(PA), which routes alllll audio signals through itself! this PA is a daemon(background service). it acts as a server between device-driver(ALSA) and the audio apps(like, VLC). for example, whenever VLC is opened, PA kicks into action and opens up an audio stream connecting VLC output to the HDMI driver.

 

whenever PC lost audio, it was necessary to run a command ("pacmd -PulseAudioCoMmanD") to launch the Command-Line-Interface of the PA daemon within the linux-CLI. PA's own command prompt appears on the terminal window. simply "exit" the module to close it. all this "exit" does is, it CLOSES AND KILLS the PA daemon.

within seconds, linux-kernel RELAUNCHES PAdaemon again, sound controller appears back on the audio output interface.

 

bam! just choose your HDMI audio output and enjoy your music!!

audio and wifi-drop are the two major problems that annoy mint newbies like me. hope this blog entry helps them all!
 

installing TOR browser on SOLUS linux!

visual appeal of deepinOS has almost no match!

everything was perfect-except installing new softwares! after multiple attempts to get its software-center work, i was defeated!

distrohopped to solusOS!

again... in solus, i had an another, luckily small problem.

installing 'tor browser' was a headache as it was not readily available in SOLUS's software center. a search in its native "software center" took years with no good result.

so, decided to install 'tor' through command line terminal.

 **************

with usual syntax, attempted to install 'tor' straightaway!

sudo eopkg install torbrowser-launcher

**************

but then, it returned with an error!

System error. Program terminated.
(-30973, 'BDB0087 DB_RUNRECOVERY: Fatal error, run database recovery -- BDB0061 PANIC: Invalid argument')

and another, along with the above!

System error. Program terminated.
(-30973, 'BDB0087 DB_RUNRECOVERY: Fatal error, run database recovery -- BDB0060 PANIC: fatal region error detected; run recovery')

 

**************

required a course correction!

System error. Program terminated.
(-30973, 'BDB0087 DB_RUNRECOVERY: Fatal error, run database recovery -- BDB0060 PANIC: fatal region error detected; run recovery')

**************

so i had to 'run database recovery'. how?*

sudo eopkg rdb 

**************

this rebuilds the database that is stuck.

once DBRecovery is complete, went for another round of

sudo eopkg install torbrowser-launcher

**************

done! we are good to go!

enjoy onion!😋
