Last week I installed ubuntu on my desktop machine. My monitor can handle a resolution of 1920x1080 with a 60hz refresh rate.

After installing the distro, I checked the display section, and the resolution for 1920x1080 is not listed in the drop-down list.

So I follow the following steps.

Step 1: Created a new resolution mode using

cvt 1920 1080

This calculates the resolution which is required for creating a new resolution mode. You can use the refresh rate as the 3rd parameter.

Step 2: Create a resolution mode

It was a plan B. Since our primary plan to go to Tanguar haor cancelled, we made a sudden plan to visit Sitakundu.

This time we find a group who were planning to trek on jhorjhori trail and Guliakhali sea beach.

We start our journey from Dhaka at night. Around 3 pm we reached feni and wait for daylight. Also, we had our breakfast there.

We reach to sitakundu around 6 PM with local transport and start trekking.

Till now, for me, it is the longest trail in sitakundu. …

We started our journey from Uttara, Dhaka. We reserved a Nissan coster for 24 team members.

We reached sitakundu morning at 6am. Had our breakfast in a local restaurant and prepare for the trekking.

Sonaichori trail is wilder among other tails in sitakundu. It took for us almost 2 hours to reach the end.

On our way, there was a Bat Cave. It was scary but enjoyable.

We started our journey from Dhaka on 15th December. 16th December was Victory day, take the vacation of 17th December and the next two days were weekend. It becomes a 4 days tour.

We plan to summit both Tajingdong and Dotong as soon as possible and spare the rest of the time in the kingdom of Khums.

We leave Dhaka on 15th December night with a reserve bus. Two teams were there. One was us and another was for summitting the yogi and yotlang.

We reach Bandarban morning at 6 am and with a jeep went to Thansi around 10…

This was the first time I joined a travel group. The advantage is you just book the tour. All the plan is organized by the agency.
