After doing an update, booting, grub screen shows. Once I entered, I got a totally blank screen.
I am using Acer Aspire 3 Ryzen 5 Quad Core – (4 GB/1 TB HDD/Windows 10 Home) Laptop (https://www.flipkart.com/acer-aspire-3-ryzen-5-quad-core-4-gb-1-tb-hdd-windows-10-home-a315-41-a315-41g-a315-41-r45r-laptop/p/itmfcfwg7yzqb5sn?affid=hiteshsal1 ) I want to use Ubuntu along with Win 10 Home for Development purpose. Can Ubuntu will work on AMD architecture? Kindly guide me in this.
My processor does not runs at its full clock speed on Ubuntu, I also tried it on Arch Distros like Manjaro and faced the same issue. Below are the details of my system and what I have tried till now.
I installed Ubuntu 18.04
4.15.0-43-generic alongside of Windows 10 Home on
Acer Swift 3 SF315-41
The Max CPU speed and other beginner details are as follows:
Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 8 On-line CPU(s) list: 0-7 Thread(s) per core: 2 Core(s) per socket: 4 Socket(s): 1 NUMA node(s): 1 Vendor ID: AuthenticAMD CPU family: 23 Model: 17 Model name: AMD Ryzen 5 2500U with Radeon Vega Mobile Gfx Stepping: 0 CPU MHz: 1574.846 CPU max MHz: 2000.0000 CPU min MHz: 1600.0000 BogoMIPS: 3992.66 Virtualization: AMD-V L1d cache: 32K L1i cache: 64K L2 cache: 512K L3 cache: 4096K NUMA node0 CPU(s): 0-7 Flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt pdpe1gb rdtscp lm constant_tsc rep_good nopl nonstop_tsc cpuid extd_apicid aperfmperf pni pclmulqdq monitor ssse3 fma cx16 sse4_1 sse4_2 movbe popcnt aes xsave avx f16c rdrand lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a misalignsse 3dnowprefetch osvw skinit wdt tce topoext perfctr_core perfctr_nb bpext perfctr_llc mwaitx hw_pstate sme ssbd ibpb vmmcall fsgsbase bmi1 avx2 smep bmi2 rdseed adx smap clflushopt sha_ni xsaveopt xsavec xgetbv1 xsaves clzero irperf xsaveerptr arat npt lbrv svm_lock nrip_save tsc_scale vmcb_clean flushbyasid decodeassists pausefilter pfthreshold avic v_vmsave_vmload vgif overflow_recov succor smca
However in windows the max processor speed is 3.6GHz
This max speed is also possible in Ubuntu as:
$ dmidecode -t processor | grep Speed Max Speed: 3600 MHz Current Speed: 2000 MHz
On some research I found that the Legacy Bootloader should be enabled and EFI should be disabled for the turbo frequencies to work normally. But my laptop manufacturer does not allows that and it has a primary Windows 10 OS.
Also is there any chance that the AMD microcode is not loaded in the init? If so, then how to solve this?
Any approach towards the problem or alternate solution would be helpful.
