No graphical display after entering cryptsetup passphrase (new aramo install from latest iso)

I installed aramo from the latest iso (24th January) on an Acer Aspire one 722-C62kk.
The installation process worked in graphic mode, I went for the automatic install overwriting the whole disk with the LVM and ciphering options. During the install, the display worked fine in graphic mode although I had the feeling that the height width ratio was perhaps not right.
After install, at boot, I get the graphical screen to type the passphrase for cryptsetup. After I enter it, I have the normal success message, the trisquel is fading and coming back a few times, then I got to text mode with a message, an error of loading brcmac (or something like that) then a blinking cursor endlessly.
I switched to a text console and logged in, I am not sure what to look at. Xorg.0.log finishes with "Server terminated with error" but I have no clue how to interpret the other contents. Perhpas the GPU is not supported? CPU description says "AMD C-60 with Radeon(tm) HD Graphics" and display says "Radeon HD 6290".
I attach logs. Any advice on how to get some graphical display is welcome.

Try to apply the latest updates, mainly the kernel ones, that should bring new info on the matter.

After installation, I did run updates and there were quite many. I just tried to update again, there is no update available, so I suppose they were applied already.
Could you confirm this is a BIOS and not UEFI?

I checked, the setup menu refers to "BIOS version", so I guess it is BIOS and not UEFI.
There is a WIP to improve the performance on the AMD cards, this is not yet finished but the Radeon driver should already be ready to test these changes, this is the case for 5.15.0-60-generic and later.
Could you try moving /etc/modprobe.d/disable-radeon.conf to your home folder for example, so it doesn't gets loaded at boot.
sudo mv /etc/modprobe.d/disable-radeon.conf ~/
then reboot and check if something changes.
Update: I think we can track better logs, outputs, and other details on the gitlab instance.

Thanks, I tried and it worked and I have the expected resolution of 1366x768. What is the reason to blacklist the radeon module by default?
Before doing the change, the boot process was different from previous times (but that happened only once):
- I saw the first error message in a much larger font
- I saw a grub menu that I never saw previously
- instead of getting a graphic screen to enter the cryptsetup passphrase, I got a text screen with "Trisquel 11.0" in the middle and 4 dots with alternating colours and then, a text message to enter the passphrase
- after that, I got a graphic screen and I can login, but the resolution is 1024x768, the display is not recognized and there is no option.
This computer has another but reproducible strange behaviour: shutdown works ok but if I try to reboot, it stalls with a fixed cursor.
Let me know if there is any use to provide some log (and which one), in case that is useful information for any kind of purpose (not for this computer, it works ok now, I don't care too much about this reboot issue, I can shutdown and press power again).
There has been historical workarounds to get the best out of Ati/AMD cards without loading the non-free firmware, AFAIK blacklisting the radeon module was part of the previous workaround trisquel has been using since around version 4.
Now days, there is an on going effort at:
https://libreplanet.org/wiki/Group:Hardware/research/gpu/radeon
Where new testing and efforts from Denis 'GNUtoo' Carikli had helped to find out we can do better, and we are now in the process of introducing these changes into aramo, hoping this will improve the life of several AMD videocards users, where before they would have needed to install linux-libre third party repository to test these changes out leaving the Trisquel LiveUSB out of the equation.
Please bear in mind that this blobless activation will NOT give you 3D acceleration of any sort, it will help detect the right resolution for most devices listed at the previos page, so you don't have a 4:3 ratio on a 16:9 device or you don't get stuck at some 800x600 resolution and it's limited to a number of known to work/tested videocards.
So is just a small but valuable improvement, by the time we get a new set of ISOs we'll be able to "see" the latest changes trisquel will start shipping with aramo.
About the text boot to enter the cryptsetup passphrase. IIRC, you can switch from GUI to text mode just by pressing the "Esc" key, not sure if that's what you saw.
I'm sure this could bring a lot of new info, but as you might have imagined only users with the specific device will find out, so if you think you have spot a bug please fill it out at the gitlab bug tracker.
Regards.

For me, this is a great improvement to have the proper ratio!

Sorry, I feel really stupid here, I have not much clue what 3D acceleration is useful or not useful for. I always disable fancy effects or animations and I don't play videogames. I do sometimes video calls or play a video. Does that use 3D acceleration?
Well, not at expert either, but yeah think of 3D acceleration a tool to draw tridimensional shapes very fast, and apply shades and colors and all the processing happens on the GPU (not the CPU).
Now, 2D and 3D can be done with software rendering, but is orders of magnitude slower, so not enough performance to play STuxkar, 0ad, or any other game build to run libraries that make use of calling the GPU.
I do sometimes video calls or play a video. Does that use 3D acceleration?
Well some new software might require it, now days that you can use dynamic backgrounds, but maybe that will relay on software rendering.
I'm glad you got the right ratio, cheers!
